Jende Kangaroo and Leather Strops – What’s the difference?

October 17, 2016

We’ve recently introduced the Jende Kangaroo and Leather strops on color coded acrylic to our lineup. One of the questions that will inevitably be asked is “which one is better?” As usual, the answer is “it depends”. They are both excellent mediums, and this article is designed to allow you to make a better informed decision about which is better for you and your particular needs.



Jende Leather Strop (acrylic side)

Kangaroo and Cow leathers are both tanned animal skins, In this case it is vegetable tanned, which is basically untreated with any oils, waxes, etc.. It’s the most natural foundation which can then be used as a clean, final strop or be loaded with pastes, sprays, compounds or emulsions of your choosing. Cow leather has a much longer history of use for stropping, with Kangaroo leather only becoming more accessible since Crocodile Dundee first appeared in the 1980s.😀


Jende Kangaroo Strop (acrylic side)

Ounce for ounce, kangaroo has about 10 times the tensile strength as cow leather, meaning a thin 1mm strip of kangaroo is about as strong as a 2-3mm strip of cow leather. This translates into less compression of the kangaroo strop over the cow strop, which can be advantageous in certain situations like straight razor honing. But the compression of the cow leather can be more suitable to matching the shape of convex edges.

In order to better describe more of the differences between kangaroo and cow leather, we need to look more closely under the microscope. Here’s a side by side macro view of the Jende cow and kangaroo leathers. Pictures are taken with a Veho 400x and the actual resolution is 1.3mm wide x 1mm high.



Cow Leather, Macro



Kangaroo Leather, Macro

At this level, the cow leather looks very consistent and smooth. There is what’s best described as a “spotted” texture to the leather, but it seems flat, overall. (It reminds me of the surface of painted drywall, actually.) The Roo, however, looks like an army of ants are embedded in the surface. These are the hair follicles of the skin. Overall, the surface looks smooth, even with the contrast of the black follicles. Honestly, there’s not much difference to be seen between the two skins here.

Where things really change are at the micro level. This resolution is 1mm wide by 0.75mm high.


Jende Leather Strop, Micro


Jende Kangaroo Strop, Micro

The spotted surface of the cow leather reveals a smooth surface with raised polyp-shaped mounds. The kangaroo leather shows a smooth surface with divots where the hair follicles are. It is this difference that really influences the the way each strop works.

My theory is that he raised polyps on the cow leather will come into contact with the blade when stropping, making the strop more aggressive but arguably slightly less consistent. If you were to load the strop with an abrasive, the abrasive would leave deeper scratches at the polyps and more shallow scratches in between. Again, arguably more aggressive but less consistent.

The divots on the kangaroo leather do not interfere with the stropping action of the rest of the surface of the strop, meaning you get more consistent contact with the strop when stropping. When the kangaroo is loaded with an abrasive, the contact between the blade and the strop is much more constant as well since the abrasive fills in the gaps. The catch here is that this could be considered less aggressive since the surface scratches are not as deep, but because more edge is in contact with abrasive throughout each stroke, it could still be described as as aggressive since there is more shallow depth of scratch per stroke, but a whole lot more of it. It’s a different kind of aggression.

So what does all this rambling mean? Well, based upon the picture evidence, there is a strong argument to be made that the polyps of the cow leather make for a more aggressive stropping medium and the divots of the kangaroo make a smoother stropping medium. This is the simple answer, of course, and doesn’t factor in things like stropping technique and pressure. But is does remain a constant that the cow leather has raised polyps and the kangaroo has divots, and this is the information needed to begin making an informed decision as to which stropping medium is better suited for your needs.

To give an example, a 2K edge on a hunting knife can get more out of a cow leather strop since it will push the edge back into position with more force. That same cow strop loaded with a 4 micron (4K) Jende emulsion takes the knife edge up a notch while still being aggressive enough to maintain the edge between sharpening sessions. On a straight razor, a kangaroo strop will push the fragile edge back into a more uniform position. The same kangaroo strop loaded with 0.25 or 0.10 Jende emulsion will abrade the edge of the razor more evenly, thus minimizing microchipping while keeping the scratches very consistent. You can just imagine the possibilities from here!

Loading and Using the Jende Nanocloth Ultra Color Coded Strops –

September 20, 2016

We’ve done a quick and dirty video on how to load your Jende Color Coded Nanocloth Ultra Strops. These are the 4 micron 2×6″ with 4 micron CBN Emulsion and the 210×70 mm 0.25 Micron Poly Diamond Emulsion. Both strops and emulsions are color matched for easy recognition. 210×70 mm strops are designed to fit most stone holders as well. These strops are 3/4″ thick acrylic.

A special thanks to Mike Martinez of Martinez Blades and to Mark Reich of Reich Precision for allowing their razor and knife to make a cameo appearance.

The New 15K Jende Reed Knife

September 14, 2016

The New 15K Jende Reed Knife is now available! The 15K Jende Reed Knife has been around since Jende Industries first opened its doors, but it has just now received a complete overhaul.

The New 15K Jende Reed Knife now features a stainless steel that has slightly more complexity and wear resistance, giving a different type of edge that can hold up longer. It is still sharpened to 15,000 grit for control and effortless removal of cane. The handle is Madagascar Ebony, and is tapered to fit hands of all sizes. The handle has been laser etched with the Jende logo and sealed with 100% natural bee’s wax. The weight of the hardwood handle helps keep a neutral balance for scraping your oboe, bassoon, and clarinet reeds. The sheath is Stone Oiled leather for stylish protection of the blade.

Jende Nanocloth Ultra Strops – Color Coded for Your Pleasure!

September 9, 2016

We are happy introduce Jende Nanocloth Ultra, our newest innovation in stropping mediums!


Jende Nanocloth Ultra Rainbow

  • The Jende Nanocloth Ultra is a synthetic stropping material that has no weave, so feedback is the same in all directions. Other weaved strops tend to have noticeable resistance change feedback variations, like a rug when vacuuming, which can make you second guess your stropping stroke.
  • The Honeycomb structure is very consistent. The shape allows the emulsions to fill up the honeycombs, keeping more abrasive on the strop and off your knife. The shape also fills up and beads on the surface, giving a snow-shoe effect with even scratches when stropping.

Jende Nanocloth Ultra – 400x

  • The depth of the honeycomb has little compression – less than leather in general.
  •  Because of the depth of abrasive in the honeycomb tubes, differential pressure can be used to give the strop more or less aggression by adding pressure for more aggression, and super light strokes to just tickle the edge for finish stropping.
  • The color-coded Acrylic base allows you to instantly recognize the grit strop you desire to use, saving time and confusion.
  • Laser etched to ensure long-lasting and clear identification marks.
  • Works equally well with our Jende Poly Diamond Sprays, Jende Poly Diamond Emulsions, and our Jende CBN Emulsions.

We are offing a huge variety of sizes on color coded acrylic, including 210x70mm and 2×6″ Bench strops on 3/4″ thick acrylic blocks, and for a full array of guided sharpening systems, including the Edge Pro (EP), Hapstone Sharpener, KME Sharpener, and Wicked Edge (WEPS).  Stropping will never be the same again!

Ken Schwartz Products Are No Longer Available

September 8, 2016

It is with great regret that we must inform everyone who has supported Jende Industries over the years that the relationship between Ken Schwartz of Precise Sharpening and Jende Industries has come to an end as of June 18th, 2016. Ken Schwartz’s products are no longer available for purchase.

There is a long, vibrant, and fruitful history between Jende and Ken, but amongst other irreconcilable differences that we’d rather not discuss publicly, it has mainly come to a point where chronic inconsistency of supply and delivery times on Ken’s part was hurting our reputation and customer service record. We have put up a notice on our website to this effect, and have since developed our own improved line of  Jende CBN and Poly Diamond Emulsions. We have also added our own Nanocloth Ultra, Kangaroo, and Leather strops to accommodate sharpeners of all types, be it free hand, mechanized, or guided. We are sorry for any inconvenience this may cause. In the mean time, we strongly recommend considering the Jende Strops and Compounds, found on our site, here.


Jende Artisan Mall – Just One of the Changes at Jende

May 27, 2016

We’ve recently made some serious changes to our website! has gotten a long overdue upgrade and is now on a much more powerful and versatile platform! One of the major changes is the addition of the Jende Artisan Mall. The Jende Artisan Mall is is a gathering place for amazing and talented artisans whose products and services compliment our own.  It’s best described as a farmers market. And like farmers markets, it’s populated with local and regional artisans who bring together the diversity, vibrancy, and creativity of the community under one roof.

Jende Artisan Mall

The Jende Artisan Mall is quite diverse, as we span a large area of all things sharpening. The purpose of the mall is to encourage our customers to discover a wider range of related artisans within the area or areas of their own interests. On the flip side, since many artisans prefer to concentrate on the quality of their products over marketing them, the Artisan Mall gives them exposure to a wider audience – and not just for exposure’s sake.

The major areas actually mirror those of the main Jende categories, and expand to more specific areas, such as custom knife makers, oboe and bassoon reed makers, shaving soaps, custom woodworking, and sharpening services, just to name a few. So we hope everyone will come by and check out the new site, and support the Jende Artisan Mall!

TOG Elite Japanese Kitchen Knives Review

April 25, 2016

We recently received a TOG Elite Japanese Kitchen Chef Knife Santoku for testing. Bottom Line: This is one very nice knife that handles well, keeps its edge, and just plain looks good.

TOG Elite Japanese Knives

TOG Elite Japanese Knives


On the TOG website, there is a “Tech Specs” page that lists all the wonderful, interesting, and even nerdy things about the knives.  I’ve decided that my review will focus around the claims on that page.

  • “TOG blades are made from a special steel… to produce the ridiculously sharp blade and ensure that it stays sharp.” 
  • “Incredible cutting performance from a central layer of high-carbon (1%) steel. This core is made from… Acuto 440 that is similar to Western ‘440C’. This is hardened to Rockwell Hardness (HRC) 58-60…”

As an OCD sharpener, any claims to sharpness are always met with (rolled eyes or yawn) “Oh, yes, it is.”  I then proceed to lick the entire edge of the blade  – twice.  :) The TOG blade, however, actually looked and felt surprisingly sharp upon checking the edge right out of the box – sharp enough for me to not employ the old tongue test. So I went straight to the paper cutting test, expecting a typical 240 grit with a buffed edge feel. I was shocked by my first cut, so much so that I took another slice into the paper just to make sure. This thing cut -no- SLICED through the paper in a way that was not the usual factory edge. This was much, much better. I was truly impressed. If I had to call the grit, I would say about 3K. Score 1 for TOG right out of the box.

Edge retention is always going to vary depending on the user and the tasks performed, but when I sharpened up the TOG to my usual angles and finish, it kept up as good as, if not a little better than my usual knives (RC57-58). The knives in the rotation were all freshly sharpened by me, and used in a professional kitchen over a 2 week period with no special treatment (believe me!), and were only adjusted with a sharpening steel by the sometimes brutish kitchen personnel.

Steel junkies say what you will about 440C, but the Acuto 440 steel in this blade is perfect at RC 58-60. IMO, RC 56-60 is the Goldilocks hardness zone for high quality, non-custom kitchen knives – hard enough to hold the edge so that it does not require steeling after every cut, and flexible enough so that the edge won’t chip out. RC 58-60 also makes maintenance on the edge easy and straight forward on just about any good quality sharpening equipment, be it a steel, stones or mechanized sharpeners. I used 220, 1K, and 4K sharpening stones and got a smooth edge with just enough bite. As a sharpener, I am quite satisfied with the quality.

As for the feel of the edge when in use, it actually felt more akin to VG-10 steel, and not even remotely close the soft mushy stuff that your 29-piece knife set in a woodblock has (usually RC ~52). The overall balance and handling of the knife was easy and light, and the thinness of the blade allowed for easy cutting and slicing.

So to sum it up, this is one very nice knife that handles well, keeps its edge, and just plain looks good.

Thank you to the fine people at TOG for the opportunity!

Breaking the Jende Ceramic Sharpening Steel

October 23, 2015

Talk to anyone who has a conventional ceramic sharpening steel and they most likely will only let you look at it from a distance – which is dangerous enough in itself – and you’ll never get to use it, of course. That is because ceramic sharpening steels are notoriously fragile, and have taken on the same stigma as the famed Ford Pinto, whose gas tanks famously exploded on the slightest impact.

Well, let me tell you – our Jende Ceramic Sharpening Steels can take some of the meanest looks out there, and even hold back the tears when getting a good verbal lashing.  The anti-break technologies incorporated into the handle, the rod and the tip allow the Jende Ceramic Steels to take a good beating, too. We’ve done a previous “bam bam bam bam bam” test, which can be seen here, and now we have done an official drop test, showing that it is now safe for your friends to at least hold your ceramic steel, even if they are not worthy of using it!

Now, as much as we’d like to, we are not claiming the Jende Ceramic Sharpening Steels to be indestructible. They employ anti-break technologies that are designed to allow the steel to stay intact if dropped accidentally, or if bumped into another object, etc. during the rigors of everyday commercial and/or home use. For due diligence, we escalated our tests to see what exactly it would take to break one of our steels, and this was the last known surviving picture of the poor Jende Ceramic Steel that sacrificed its life in the name of science. His name was Brian, after the bastard that killed him.
