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 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...

They fit my Ken Onion work sharp perfectly, quality seems the same as the name brand, but time will tell :)

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.

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.

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'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.

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.

I’ve got the Makita cordless file that I use these belts on and it’s my favorite power tool by far. However the belts that come with it snap very easily. These do not EVER break, last quite a long time and work perfectly for a myriad of things, but excel at sharpening. Buy them, you will not be disappointed.

No son tan buenas como las originales que fabrica la marca Norton, pero están bien para el precio, cumplen su función aunque obviamente se desgastan mucho más rápido que las originales, la ventaja es que tienen mucha más variedad, las originales no vienen en tantos tipos diferentes.

No comment. Best buy ever

Excellent. Have had a WSKO elite for years, always used the WSKO belts - I still will for some work, but these are far superior and less expensive. They are as advertised - 3M on the belts (most). They are the same as the belts I use on my bigger machine - I use cubitron and trizacts and that’s what these are. They move metal fast, cooler than normal belts and cleanly, fit extremely well and having a 2500 grit is great. Will buy again

Does the job well

The sanding belts arrived quickly and the slightly finer sanding belts seem to be ok. The green ones (the coarsest) are so hard and stiff that they are almost useless. The machine(Worksharp Ken Onion) vibrates strongly with these.
