February 9, 2017

The Jende Hapstone V6 is now in stock! This is the first collaboration with Jende Industries and the Hapstone Sharpener. We’ve got the V6 sharpener tricked out with the Jende red and black colors, as well as a couple of other goodies.


One of the benefits of the Jende Hapstone V6 aside from its striking beauty, is the option to accessorize like mad – you can choose from a full line of Shapton Glass stones, Chosera stones, and from our complete line of Color-coded Jende Nanocloth Ultra Strops with CBN and Poly Diamond emulsions as well as our Kangaroo and Leather strops!

And if that was not enough, the Jende Hapstone V6 also has a rotary sharpening attachment, which clamps blades and rotates them without the need to move the knife at all!


So if you’re in the market for a new sharpener. make it a Jende Hapstone V6!



KME Sharpener Chosera Stone Introduction

April 6, 2014

Tom Blodgett of Jende Industries demonstrates the Chosera stones available for the KME Sharpener. In terms of guided sharpening systems, the KME is one of the best systems on the market. With the Chosera stones now available for it, it adds a whole new level of versatility. There is a nice surprise at the end, so please do enjoy the video in its entirety. 🙂

In this video, I prepared the initial edge on this knife with the stock KME diamond plates at 22 degrees per side, and then used the 1K, 3K, 5K, and 10K Chosera stones.

There are 8 Chosera grits in all:

400, 600 & 800 are best for initial profiling, repairs and make great transition stones from the stock KME diamond plates. These stones leave an aggressive, toothy edge. The 800 leaves a very good “working” edge.

1K, 2K, 3K are best suited for maintenance and light repair. These stones refine the edge that is on par, and often better than more traditional sharpening levels. The 1K is an excellent “working” edge, and the 2K and 3K leave an edge that easily slices, but still has a little “bite”.

5K & 10K stones are truly polishing stones – they take the sharp from the 1K, 2K, and 3K and polish/refine the edge even further – these are the game changing grits. The knife will slip effortlessly through things, and yes, you can shave your face directly off the 10K. It is a great platform from which to continue on to even higher finishes using the strops and compounds available for the KME.

You can find the KME Sharpener and Chosera stones on the KME website, and the Choseras for the KME are also available from Jende Industries, LLC.


1″x6″ Chosera Stone Straight Razor Microscope Progression

March 29, 2014

When it comes to honing razors, my go to stones are the 1″x6″ size. This is because many of the vintage razors out there have some sort of warping, smile, frown, or years of uneven hone wear that makes it very difficult for the full size stones to fix without either removing a lot of steel from the blade and/or causing a lot of unnecessary hone wear. Not to mention, the time and frustration it can cause, especially to newer honers. Simply put, the 1″ wide stone can do a better job in many of these cases, not to mention saving money, space, and having much greater portability.

With more people using the 1×6 stone size, I put together a micrograph progression of what an ideal bevel/edge looks like at each of the Chosera grits. The razor used was a Geneva Cutlery (NY) 1/4 hollow ground that was already in shaving condition. In the case of this razor, the average stroke count was approx. 150 alternating askew X-strokes. All pictures are taken on a Veho-400 USB microscope and the actual picture size is 0.75 mm tall by 1 mm wide.

1. Chosera 400

1. Chosera 400

With the 400 and 600 Choseras, the edge is pretty even, but rugged. More importantly, if you look at the top ridge, it is actually pretty “thick”. So while it is even, it is still too thick to cut into arm hair with ease.

2. Chosera 600

2. Chosera 600

The 400 and 600 Choseras are probably best for cleaning up deeper scratches from diamond plates and for repairs.


3. Chosera 800

3. Chosera 800

The 800 Chosera is a bevel setting stone, as well as a transitional and repairing stone. Notice the bevel has a matte finish, and the ridge, while slightly wavy, is noticeably thinner – but still too thick for cutting hair. This edge will cut arm hairs with some pressure.

4. Chosera 1K

4. Chosera 1K

The 1K Chosera is a bevel setter, and can handle minor repair/touching up. The bevel is beginning to get smoother and brighter, and the edge of the edge is beginning to become more uniform. It is very important that the 800 and 1K stones are done as perfectly as possible to prevent more work at later stages. This edge will cut arm hairs with a little pressure.

5. Chosera 2K

5. Chosera 2K

The 2K Chosera begins to polish the bevel and refine the edge of the edge. The ridge line is still slightly rounded, but is much more uniform. More importantly at this stone, the bevel is not revealing any hidden deep scratches that will cause micro chipping later. This edge should cut arm airs with little to no pressure.

6. Chosera 3K

6. Chosera 3K

The 3K Chosera adds more polish to the edge, and brings out the bevel’s surface even more. The ridge line of the razor may look frayed some, but you are almost looking “into the edge” at this angle. This is the micro chipping effect, which is inevitable, but it is of the 1K and 2K scratch level, which will clean up. It may be worth adding more strokes to this level, or jumping down a level or 2  if there is too much fraying. This edge should cut arm hairs with little to no pressure.

7. Chosera 5K

7. Chosera 5K

The 5K cleans things up. there will always be an element of a frayed edge, but the line is very even and the depth of the frays terminate very quickly. You cannot do too many strokes at the 5K level. This edge should cut arm hair effortlessly, and it should feel like it shaves (I don’t recommend it, though!)

8. Chosera 10K

8. Chosera 10K

The 10K Chosera really brings a polish to the bevel and the edge is very consistent. Like the 5K, you really can’t do too many strokes on the 10K, but if you are getting frayed edges, you need to step to the 5K or back as far as the 1K, 2K, or 3K to clean them up. This edge should slide through arm hair effortlessly.

After this, you can strop and shave, or continue with further refinement.


Setting a Straight Razor Bevel on a 1K Chosera EP Stone (Video)

March 14, 2014

I was asked to show the best way to set a bevel on a 1K stone, in particular on a Chosera 1″x6″ Edge Pro sized stone. FWIW, I do the majority of my razor honing on 1×6 stones because the 1″ width can easily accommodate most warping, frowning, and smiling blades better than a full sized 3″ width stone can. It’s a personal thing for me, as I have all the corresponding full sized stones as well, but for others, it is also a space and money thing.

Anyway, there are 3 basic strokes demonstrated in the video: Circles, Knife Strokes, and X-Strokes. There is a synopsis below the video. Enjoy!

Circles – are the most aggressive action, and are best for repairing chips or creating an initial bevel on a razor that is in need of serious restoration. I generally do sets of 20-25 circles per side with pressure. It may take many sets to do what needs to be done, but this is the stroke to get that work done. Once a bevel is established using circles, it will need to be refined with knife strokes on the same stone before moving to a finer stone.

Knife Strokes – are single sided back and forth strokes made without turning the blade over. It is “half an X stroke”. This stroke is best for light repair, or a quick refresh of a tired edge that has been maintained for a while. It uses less pressure than the circle stroke, and cleans up the messy edge the circles make. I generally do sets of 20-25 strokes per side. You shouldn’t need too many sets to accomplish your goal here if you’ve used circles, but if you start here, it may take several sets.

X-Strokes – are the usual method of alternating, single side honing strokes, and uses no pressure. This is the least invasive method, and the one that prepares the bevel/edge for the next grit level. I recommend at least 50-100 strokes to firmly establish the depth and consistency of the 1K stone. This will help prevent micro chipping at higher levels.

When to use each stroke?

If your razor is an Ebay special, or has serious restoration issues, then you will want to start with circles, clean up with knife strokes and then finish with the X-strokes – all on the 1K stone.

If you are maintaining a tired shaving edge with maintenance wear, I would begin with the X-Strokes, and if more aggression is needed, move to the Knife Stroke, and if it is really bad, resort to the Circles (and then work you way back up).

I hope this helps!

Jende Industries, LLC 2012 Sharpening Party!

July 19, 2012

After a short 2 day break from my travels to Chicago and Austin, it was finally time for my Sharpening Party! Ken Schwartz from Precise Sharpening flew in the previous evening, and we had a chance to catch up again – after only 2 weeks since seeing each other at the BLADE show in Atlanta 😀 Greg (Dudly the togi from the knife forums), John Fortune (Hone Ranger), and Ron Swartz of KME Sharpeners arrived with lots of goodies in tow! Greg brought his sword polishing station, complete with stones and a couple of Katanas, John brought the all important Arizona Iced Tea along with a few sharpening goodies, and Ron brought his KME Sharpener with about 20 different accessory stones, including the new Choseras.

Having Ken, Ron, John and Greg would’ve easily been more than enough for an all day sharpening “meeting of the minds,” but we took this party to an all new level – we went international, baby! That’s right, we hooked up our laptops and had Skype video calls from Belgium with Michiel Vanhoudt from Belgian Sharpening, and Jens Skandevall (our famous – and crazy – shaving competition winner) from Sweden.
And this was completely interactive – Jens and Michiel were honing razors in front of each other (we turned the computers toward themselves 😀 ), Michiel gave Ron a Belgian coticule/BBW tutorial, and then we all watched with complete amazement while Greg blew our minds with his sword polishing demo, which took us all too quickly through just about the entire process (obviously not on the entire sword, which would take over a week).

International Skype Call

Greg’s Katana Polishing Demo

We were in the garage for the sword polishing demo for about 2 hours before we decided to head inside for some much needed AC!

Once inside, the fun continued – we brought Michiel and Jens in with us, and we all continued to sharpen stuff – Ron broke out his EDC, clamped it into the KME sharpener, and we documented the entire Chosera series on the KME on the microscope. Ken started bringing out all kinds of Nubatama stones – Japanese naturals and synthetics – for Greg to play with, and John started in on a Maestro Wu folding knife with the Atoma diamond plates for the Edge pro. I played with a few EP stones that John brought and generously gifted to me. Jens started sharpening some knives while Michiel honed up a razor or two. This was just too much fun!

L-R: Greg, John, Ken, Ron

Geeking out with the loupes and microscopes!

The fun continued until about 5pm, when we took a dinner break. This was a 7 hour marathon, and Michiel and Jens lasted over 5 hours with us, and John had to head home to his family ( a few hours later than anticipated!). Since Ron took Ken and me out to the Longhorn steakhouse a few weeks earlier, we decided to return the favor.

After the wonderful steak dinner, Greg took off, and Ron, Ken and I returned to the kitchen to sharpen even more. This time, Ken broke out his famed CBN sprays on Balsa, and put them on Ron’s KME Sharpener. I must say, that CBN is totally awesome, and it works so much faster than you would think given it’s just a spritz or two on the balsa! We continued the sharpening madness until around 11pm, a full 13 hours since we started.

It was really great to spend time with John and Greg again, and for Michiel and Jens to watch us patiently for so long (even though they were included in on the conversations). This was the first real significant amount of time Ken and I got to spend with Ron since he picked up the Choseras for the KME, and I must say, we all got along grandly. What was most amazing about this party was the fact that we all sharpened only 1 knife the entire day – not because we were slow, but because we were able to take the time to discuss and explore things in depth, rather than having to bang out a bunch of knives like we would at a trade show or convention.

What a great sharpening party!

2012 BLADE Show

June 12, 2012

The Blade Show 2012 in Atlanta, Georgia started off great! For some reason, the travel gods were favorable. On my 14 hour flight from Hong Kong, the middle seat in a row of 3 was empty and I received a free upgrade on my rental car!

I flew in on Thursday and first met up with Ken Schwartz and some of his family, and while enjoying the finer aspects of the Kao-Liang Liquor I brought and some Green Label Johnny Walker Scotch, we had one of the most intellectually stimulating conversations that ranged from knives to liquor, to salt, to bread, to music, to physics and ended with quantum mechanics.

I had a feeling that this was going to be a great blade show!!!

On Friday morning, Ken and I headed over to the Blade show and met up with Mark Reich (aka YTriech) for breakfast and it was just like old times! We saw some of Mark’s knives he had been working on, and we were blown away by the level of diversity in the blade styles as well as the handle materials and shapes. Mark said he wanted to explore and develop his own style more, but judging by the work I saw, he’s definitely developed some mad skills and the true characteristic of his knives has already begun to emerge.

After breakfast, we headed over to the show, where we met up with Clay and Kay from Wicked Edge as well as Ron, Mike and Carla from KME Sharpeners. The convention hall was organized much better this year – it was more open and less compartmentalized than last year’s show. There were LOTS of tables and vendor booths, and the place was a beehive of activity with everyone setting up and getting to see old friends.

I spent the day with Clay and Kay over at the Wicked Edge booth. Clay unveiled some of the improvements to the WEPS, which included paddles with built-in inclinometers. He also brought a more precise arm with a universal bearing joint that had no play and amazingly smooth action that was coupled with a mechanism for fine tuning the angles that literally blew me away.  I really liked the Wicked Edge before, yet somehow Clay made me like it even more! I can’t wait to get these modifications for my WEPS!

As promised, I brought my Shapton and Chosera Wicked Edge stones, and set up. When the doors to the show opened to the public, it was a mad house. The Wicked Edge booth swarmed with people trying to get in, and of course, the knife sharpening began. It was great to see Clay sharpening from the corner of my eye – he really is a talented sharpener, and everyone commented on how much they loved their Wicked Edge.

One knife after the other was handed up to us for sharpening I kept hearing CPM145, S30V, and S90V. While Clay focused on the using WEPS stock Diamond and Ceramic stones, I treated people to the awesome refining power of the WEPS Chosera 800 and 2K (due to the sheer number of people in the booth, I just did not have the time to take knives up to the 10K level.)

One knife in particular that I had fun with was a beautiful knife made by Nicholas Sass. While a lot of the knife makers I talk to generally don’t spend as much time sharpening their knives as they do making them, It was refreshing to hear just how adamant Sass is about his knives being sharp. It took a little effort to reprofile the hardened 440C (I think), but once he saw the resulting 2K Chosera WEPS stone edge, he was all smiles – He even came back with his girlfriend’s knife a little later! 😀

After an afternoon of non-stop sharpening on the WEPS, Clay, Kay, Ken and I hit the hotel bar for a drink – but not before Clay and Kay took a swig of the Kao Liang Liquor I had brought them J . We had a wonderful discussion about the future of the WEPS, and I can tell you that there are a whole lot of great innovations in the works!

On Saturday, I was eager to spend some time at the KME Sharpener booth. At last year’s BLADE show, I was really impressed with the quality of the KME, because they took all the faulty aspects of other guided rod sharpening systems and fixed them. In other words, there is no play AT ALL in the rod when sharpening, making the edge angle super precise. Another great feature is that the knife clamp rotates, which means you don’t need to worry about changing the position of the knife as you progress through the grits, and you don’t need to switch hands or be ambidextrous when you flip the blade over.

To be honest, I was so impressed with the KME last year, that I bugged them for a whole year to add the Chosera stones to their already versatile stone lineup, which includes DMT Diamonds, aluminum and silicone oxide stones and hard, black and translucent Arkansas stones. Ron finally caved in, and the Choseras for the KME finally made their debut!

When I got to the KME booth, Ron already had a few people gathered around him as he patiently demonstrated his sharpener and walked them through the sharpening process step by step on the KME. It was great to see Ron taking such care of his customers, and with his reading glasses nestled halfway down his nose, he had a rather grandfatherly feel to him (even though he’s not that old). While I already knew that Ron was deep down the sharpening rabbit hole, I could easily see in person just how much loves to sharpen, and how much he cares that others sharpen well, too.

Mike, Ron’s brother, was happy with the result of the Choseras, and we started playing around with some ideas of progressions. While he left off at the translucent Arkansas and progressed on the 2K, 5K, and 10K Choseras, I proceeded to sharpen his EDC from the ground up, first using the DMT Extra coarse, and then doing a full, 8 stone progression on the Choseras up to 10K.

As people filled up the booth, a ceramic knife came along for sharpening. Ceramic knives require the use of diamonds since they are very hard and abrade rather slowly. Since The KME uses 1×4” DMT diamond plates, I was eager to take up the challenge.

There were chips in the edge that needed to get removed, and after a few minutes, the chips were brought down, and I progressed through the rest of the DMT diamond plates. The customer was happy, and the KME was successful, as usual!

Ron, Mike and Carla had their crowd under control (I was actually getting in the way!) so I snuck out of the KME booth to spend some time walking around with Ken to see the exhibits. There were lots of knife makers, all showing off great work, and we stopped by a bunch of tables and booths including Stephen Fowler, and Travis Wuertz.

As usual, time flew by, and before we knew it, it was time to start shutting things down for the day. Ken and I packed up and said our goodbyes to Kay and Clay before heading out to dinner with Ron, Mike and Carla. Mark, and Ron’s old friend Kelly (who was at the booth with them all day) came out to have dinner with us at the Longhorn Steakhouse, and we had the best of times over a great meal. Mike was more than impressed with the 10K Chosera edge I put on his EDC earlier. After dinner we parted ways, but not before they agreed to come out to my next sharpening party (which is the 30th of June).

After Dinner, Mark, Ken and I went back to the hotel and spent the next few hours contemplating how to take over the knife world, and I gave Mark a few straight razor blades that needed new scales. He (we) got really excited about some of the materials for the scales that he was going to try. We ended well after midnight, and after a group photo, Ken and I went back home to get what seemed like only a few minutes sleep before heading out to the airport.

It was truly a great BLADE show!

Wicked Edge (WEPS) Tutorial – Lapping Chosera and Shapton Stones

May 14, 2012

In this Wicked Edge Tutorial, I take a deeper look into lapping the Shapton and Chosera WEPS stones using the diamond WEPS plates as well as the full size (3×8) Atoma Plates. You may remember that I briefly covered lapping the Chosera WEPS stones in the first Wicked Edge Tutorial, found here.


Wicked Edge (WEPS) Chosera Stone Video Tuturials – Part 1 and 2 + a Shave!

April 22, 2012

Clay Alison of Wicked Edge Precision Sharpener (WEPS) recently asked me to do a tutorial on the Chosera stones for the WEPS, and rather than write up another of my famous long-winded posts, I tried my hand at a video tutorial.  We ended up with 3 videos 🙂

The first video is the introduction to Chosera stones, and touches on flattening/cleaning the stones, as well as adjusting angles to account for the different thickness between the Choseras stones and the stock WEPS. (Read more about that here). I also go through the 3 different strokes that I use on the WEPS – Circles, Scrubbing, and Sweeping, and show some nice microscope pictures along the way.

The second video is the actual sharpening of a 3.5″ Maestro Wu Bombshell Steel folding knife using the 400, 1K, 3K, 5K and 10K Chosera stones. It’s a bit long because I wanted viewers to see a “real time” version. Due to the repetitive nature of the process, there was editing on the higher grits, where you should have the idea of the process and the time it takes by then. I finished with the WEPS leather strops with one side loaded with Ken Schwartz’s .125 micron CBN, and the other side with clean leather. More microscope pictures are posted along the way.

The third video is the same Maestro Wu knife put to a straight razor shave right out of the WEPS. It’s not my most controversial shaving video (like these!),  but there are some good closeups and the music is nice! 🙂

A special thanks to Colin Brown of ModelMosa for the use of his studio, and to Trevor Joines (TVGUY101), my cameraman and video editor.

Spyderco Military in s90v – Shave Ready

February 6, 2012

A while back, one of the members of the Keeping Sharp area of Knife Forums challenged me to sharpen his Spyderco Military in S90V. When I got it, it was pretty darn sharp already – there was a chip in the middle of the blade, but the tip area was sharp enough to cut hairs off my arm.

I can tell you that the Spyderco Military s90v is a wonderful knife -I started off using the Shapton Glass stones, an the knife just took an amazing, super scary/aggressive feeling edge up to the 4K level.After that, it was a ton of work because there was a point of diminishing returns – as each grit became finer, it took longer to cut through the steel.

I had the knife cutting smoothly from the beginning, but it just took 4 tries to get it sharp enough to cut hair comfortably. Even at the time of the shave, it only whittled hair, not popped. You can see how thrilled I wasn’t as the shave progressed, but the end result was much better than I had ever imagined when I applied the aftershave.

A couple of things I noticed – one is that while the steel is abrasion resistant, it was still prone to some rolling of the edge as it got so thin. I initially started with a 16 degree angle on each side, and went through the WEPS 100/200/400/600/800/1K diamonds, then on to the Chosera 800, 2K, 5K, 10K with a little help from some Hand American .25 micron diamond to help speed up the cutting a little. (it helped, but I really did need diamonds all the way here!) but the test shave off that was horrendously rough.

I then upped it to 18 degrees and used the 15K Shapton with the HA .25 and then the 30K Shapton with Ken’s .050 Poly. This put the edge in the right place, but not enough to shave yet. I went back and did A LOT of stropping on .25 diamond on felt and then .050 poly on balsa at about 30 degrees per side. Then some canvas stropping and some clean leather (Tony Miller strop).

The second is the fact that the knife shaved waaaay better against the grain than it did with the grain – the exact opposite of what it should do! My guess is that the resistance offered by the hair against the grain allowed for the edge to “grab on” to the hair in order to cut it.

The edge under the scope was perfectly straight and smooth at each attempt – this leads me to believe that while the carbides may be tough, the steel around them sort of “fell out” as the edge of the edge approached “shave ready”. The knife was “sharp” way early on, but getting it to shave was the real challenge.

This was just a warm up – the true test will be my Rex-121 Mule made by Farid… Stay tuned!

3 Shaving Videos with 3 Different Maestro Wu Cleavers – OMG!

September 17, 2011

Warning – In all seriousness, please do not attempt to do this without a mastery of the proper wet shaving techniques – it is extremely dangerous.

The people in the following videos are actually all experienced straight razor shavers and are skilled razor honers who have all been deemed legally insane, crazy, unhinged, and even nuts by the highest authorities across several shaving communities. For more information about Maestro Wu’s knives, please visit or

I’m not sure how these videos ended up coming to be, but I think someone one the knife forums posted a video of himself dry shaving his goatee off with a 240mm kitchen knife, and someone said they could do that with a cleaver, and well, here we are  🙂

The first video is of yours truly, Tom Blodgett, aka, jendeindustries. I’m using a Maestro Wu D-4 Cleaver that was honed using he Wicked Edge Precision Sharpener (WEPS) with  Shapton Pro stones up to 30K, finishing with Ken Schwartz’s .125 micron CBN (see my microscope progression of the honing process here). I have been shaving with straight razors for over 9 years, but only 1-2 times per week.

Next up is my good friend Michiel Vanhoudt of Belgium with his Maestro Wu D-11 Cleaver. He’s pretty new to the straight razor scene, but he is an extremely talented and experienced sharpener and fast becoming a major force in the straight razor honing world. I was secretly hoping he’d slice his head clean off, but alas, the only head that got sliced was that of a pimple on his chin.  🙂  His progression used the Edge Pro with custom cut  Shapton Pro #320, 1k Chosera,  then 2K, 5k, 8k, 15k Shapton Pros for the Edge Pro followed by 0.5 CBN, 0.5 CrO, 0.125 CrO, 0.125 CBN horse (all on balsa), and finally stropped with Clean horse from Hand American.

Next is my good friend Jens Skandevall from Sweden, aka, Honed and Bengt-Hans with his custom Maestro Wu Damascus D-11 Cleaver.  Jens probably has the most straight razor shaving experience out of the 3 of us. He free-hand sharpened his cleaver using full sized Shapton Pros 1.5K, 5K & 8K, then the Naniwa Superstone 10K . He finished by stropping with HandAmerican 0.50µ and .25µ Mono Diamond on leather, back to Hand American 0.5µ Chromium Oxide on balsa, then on to Ken Schwartz 0.1µ CBN on balsa & finally with Ken’s 0.025µ poly diamond on kangaroo. – Say that 5 times fast! This shave includes 2 parts below. Part 1 is With the Grain (WTG), and part 2 is Against the Grain (ATG).

AND Since someone is going to get the bright idea to attempt a large knife shave after watching these videos, please watch  this tutorial video I made about shaving using a Maestro Wu A-5 Damascus 10″ Chef Knife. I know the knives will be sharp, but it will hopefully save some of you crazy yahoos from lopping your head off because of poor shaving technique.  (BTW, the technique in the 3 videos above is all acceptable, it some of the others out there I’m referring to below.)


Edit: Another video with a Maestro Wu D-11 has surfaced – this is the one and only Ken Schwartz of Precise Sharpening, and the granddaddy of the sub-micron CBN and poly diamond sprays out there on the market. This video is not for the faint of heart! (yes, he makes it out alive – but I don’t know how….)
