Jende Sharpening Tips: Jende E.U. Single Bevel Reed Knife

February 21, 2019
Sharpening Tips from Tom Blodgett at Jende Industries. Sharpening a single bevel Jende Reed Knife is almost the same as sharpening other single bevel knives. The front face is hollow ground, so that gets sharpened flat on the stone, much the same as others. However the back face or bevel side, which is usually sharpened at the more obtuse bevel angle, has been thinned to allow the edge bevel to have a longer lifespan and to make sharpening and maintenance easier over time. The bevel is sharpened by raising the blade up until a “flat” is felt on the stone. You can also mark the blade with a sharpie to see where you are abrading. Once this angle is determined, that is the angle to continue sharpening with on the bevel side.

Making a Slurry on Natural Stones

February 10, 2019

Sharpening tips by Tom Blodgett of Jende Industries

Natural stones can often benefit from making a slurry. The slurry is made with a small piece of the same stone, or in this case, a 600 diamond plate.

The slurry is usually white in color, and makes the stone more aggressive out of the gate. This is especially helpful when transitioning from diamond plates to natural stones since the diamonds leave much deeper scratches than naturals.

Lost Art of the Local Sharpener

January 29, 2019

I ran across one of the last of a dying breed today – the local street sharpener working out of his modified motorcycle. His equipment is simple, yet effective: a stone grinding wheel for chips and repairs, a sandpaper flap wheel for the majority of the sharpening, and a very worn out 2×32″ belt for finishing.

He plugs his power cord in at the local shop he is visiting. He had a few other odds and ends for straightening blades and an oil stone he said he long since stopped using since most of the knives are poor quality steel these days.

We had a wonderful conversation, discussing some of the other sharpeners in town and how he is happy to be mobile and independent service without a storefront or employees to worry about. He got his start when his brother learned sharpening in Japan and set him up with the equipment he has been using since (the belt grinder needed a little knowing nudge to begin working).

He had no illusions of his purpose and his quality. More experienced sharpeners watching this video will no doubt have a lot to say about it, but he charges very little per knife and comes by every week or so. Several years ago, I would’ve been snooty and pointing out everything he did wrong. But experience has taught me some humility and perspective, and I truly praised his work, and will appreciate this chance meeting and this modern day reflection on his function in time and in the community.

Chosera Slip Stones 1×2″

January 15, 2019

1×2″ Chosera slip stones are the perfect stones for those little jobs! Carefully shaped with 3 different usable surfaces and 8 grits from 400 grit to 10K, they can fit into your glove box, field pack, first aid kit, bugout bag, tool box, or tackle box. One long surface is rounded over for use on recurves or scalloped serrations, while the other is shaped to a V for tighter serrations or small surfaces like wire nips, or field saws. The top and bottom flat surfaces can be used for conventional sharpening.

We’ve bundled these into 3 choices – a coarse set with 400, 600, 800, and 1K grit; a fine set with 2K, 3K, 5K, and 10K grits; and full set of 8 grits.

Sharpening a meat cleaver on a sharpening stone (part 2)

December 21, 2018

This is a continuation of “sharpening a meat cleaver on a belt sander” After making the shape on the belt sander, we use the 320, 1K and in this case, the 5K stones to further refine the edge. We continued using an askew stroke to make the edge a consistent shape and thickness from heel to tip. We matched the 20 degree bevel, and also used a slightly lower and slightly raised angle to make a slight convex shape to the bevel, which helps make it more sturdy, and adds a level of aesthetic beauty.

Sharpening a Meat Cleaver on a Belt Sander

Sharpening Tips by Tom Blodgett of Jende Industries

Sharpening a meat cleaver on a belt sander using two different positions of the blade will help to make an even bevel that will cut better and last longer. First step is with the blade perpendicular to the belt, and the second step is askew. The askew position increases the surface area of the edge being abraded, and therefore makes it more consistent. See the rest of the sharpening done on stones, here.

Jende Sharpening Tips – Leather & Roo Strop Loading

December 18, 2018

Jende Sharpening tips byTom Blodgett at
Loading the Jende Leather and Kangaroo strops with the Jende Poly Diamond Emulsions is quick and easy. Spreading a thing coating of emulsion evenly across the strop’s surface, let dry for about 1 hour, and use. Too much emulsion will dry too thick on the surface and be wiped off immediately upon first use.

Jende 12 Micron Max Concentration Poly Diamond Emulsion vs. chip in 52-100 steel edge

December 17, 2018

Jende 12 Micron Max Concentration Poly Diamond Emulsions was loaded onto a Jende Nanocloth Ultra Strop, and was used to monitor the cutting action of a chip on a blade made of 52-100 steel. Microscope pictures were taken every 20 strokes. Overall, the change in the chip size was approx 0.010mm, or 0.005″ over 200 strokes. While there may be errors in measurement readings, the chip’s top-most portion was clearly altered from beginning to end., as well as the level of finish on the surrounding bevel/edge.

Jende Sharpening Tips – Using the Jende Nanocloth Ultra Strops

December 4, 2018

Sharpening Tips from Tom Blodgett at
Using the dynamics of the Jende Nanocloth Strops once loaded with Jende emulsions allows you to tickle the edge by stropping with no pressure, or by using pressure to compress the nanocloth, which exposes more abrasive, making the stroke more aggressive at the same grit level.

Strops: Jende Nanocloth Ultra, 0.25 micron in 1×4″, 1×6, 2×6″, and 210x70mm
Emulsion: Jende Poly Diamond Emulsion, 0.25 micron
