1 x 18 Inch Sanding Belts,Knife Sharpening Belt Kit Fits Work Sharp Blade Grinder Attachment of Ken Onion Edition Knife & Tool Sharpener,2 PCS Each of 120, 240, 400, 600,1000 2500 Grits,12-Pack

These are crazy good, better than the OEM belts from Work Sharp. This set is complete and will do any thing you want on the tool. Stop looking and buy these.

The sanding belts are sturdy and work well. I wish that there were more finer grit belts in this selection as I rarely use the coarsest grits. These have worked well in my Ken Onion sharpener and seem to last for many knife sharpening sessions.

These belts do an excellent job for re-grinding and sharpening knives. The longevity is impressive, and the grit progression helps achieve a very refined edge when viewed through a jeweler's loupe. I usually find some nit pick for a product review, but for these I just can't. They do an amazing job, and I'll keep buying them. Until I replace my 2x72 grinder anyways...

I purchased this 1”x18” belt kit as a cheaper substitute for the original belts that came with the Ken onion edition of the work sharp blade grinding attachment. I was pleased to see that they were manufactured by 3M which is a quality name brand company that I’m familiar with and I use other products made by them. This was a big plus especially for the price. For those that don’t know , The original work sharp belts are produced by Norton abrasives.Once I started using these belts was able to sharpen multiple styles of pocket knives from blunt dull to shaving sharp in only a few minutes each. So far I am pleased for the price. I can’t speak to the longevity just yet but they seem like they will be pretty good. I do wish the kit came with a couple higher polishing grits as the highest is 2500 grit. The original work sharp belts that came with my sharpener had a 3000, 6000 grit and a 12000 grit. The other thing I noticed was that the 1000 grit and 2500 grit 3M belts both felt a little rough compared to the Norton belts of similar grit. Im not sure if it’s because I haven’t used them enough yet as they did soften up a bit after use but the original work sharp belts seemed less abrasive than the 3M on belts above 1000 grit. Overall I’m happy with my purchase especially considering cost.

I've gone through multiple sets of belts sharpening my knives and pretty much never have an issue with these belts. I was able to get through resharpening all the pictured knives after a recent camping trip with the belts in this pack + a few 5000 grit belts and a strop with bark rivers 1 micron cbn emulsion. All knives shave like butter now. Have only ever had one belt break on me, which is pretty good considering how many if gone through at this point. Sharpening some pretty hard steels (3v, magnacut, s90v) and they hold up well enough considering generally diamond stones are the recommended for those steels. My go to when it comes time to do some maintenance on any of my knives.

This is my first time purchasing an aftermarket brand of sharpening belts different from the Work Sharp brand of belts, and I’m very satisfied with the results I achieved.I have the Blade Grinder attachment for my Ken Onion knife sharpener, so I ordered the 1” x 18” set of belts. Two sets of six grit levels (12 belts total) for $16 is a good price.The pricing is irrelevant if the belts don’t work, but I think I got the best results I’ve ever achieved with these belts. I especially like their 2500 grit finishing belt. All of my knives, from 3” paring to 15” slicing turned out great.It will be interesting to see how many sharpenings I can get out of each set (I’m guessing 3-5), but for this price, it won’t really matter. They work for me.

I have sharpened and few knifes using these belts and the belts are still in good shape.

Wish it came with a higher finishing grit
