Red Label Abrasives1 X 18 Inch Coarse P80 Grit/Medium P320 Grit/Fine P800 / Ultra Fine P5000 Grit Knife Sharpener Sanding Belts, 10 Pack (Fits Work Sharp Ken Onion Blade Grinder Attachment)

Works a treat on your blades. Re-profiled without issue, sharpening till hair popping sharp, and didn’t wear out after heavy use. Get these for your Ken Onion replacements.

You can easily know the grain size by looking at the print on the back of the belt, so I think that is better than the work sharp belt. I just wish they had put 2000 or 3000 between 800 and 5000. Then it would have been perfect. I think the quality is good.

Allgood

These are great and they hold very firm, perfect for a toothy flat grind. My favorite 120 for the worksharp belt grinder attachment.

I only received my belt set today, so longevity can't be answered, BUT...they are very supple,well made German high Quality abrasives. Assembled here in the USA,they have an excellent tape joint, and I tried all the belts on my Ken Onion Grinder, all tracked well, were smooth and quiet and the tape joint made very little noise at both Low and High speeds. Some have stated they 'Stress' the Grinder attachment or it's bearings??, yet I don't see how, 1st of all, the grinder self tensions, 2nd they are more flexible than the Factory supplied belts. I also like that they are Clearly marked by color AND Grit, (ex 320,800,5000) and Grit is Marked on the back. No 'X4' or 'X22' like WS factory belts. I tried the 80 grit to shape some new,unground carbon steel, about 3/16" thick, it was no match for the 80 grit green belt. Profiled my 25* base brind quickly, and I barely see any wear, abnormal, or otherwise. Good Stuff here! Buy with confidence, these are excellent. Will be my 'Go to' for belts from now on! Thanks Red Label.

Really good for quick stock removal. I was very impressed with how well these belts took a pitted Shun knife back to flat. I will say that for whatever reason they seem to be so stiff that the Ken Onion blade grinder attachment pulleys have a hard time turning the belt initially. I'm going to have to be really careful with these I think. I would not recommend putting any pressure at all on whatever tool you are working on.

These are better quality than other belts I ordered. Well made and well labeled, they run 'slender' and smooth on my handheld kitchen sharpener. I bought other black oxide belts with a more traditional construction, which are not as well made or labeled. These are the ones I would get again next time.

I ordered these belts of course because they were about 5 dollars cheaper than the work sharp branded ones. Unfortunately, amazon delayed my package for 2 weeks but that isn’t the fault of the company. The belts work great and cut quickly.I had an issue with one of the lower grits so I called the company directly and they sent me replacement belts at no charge the same day! The guys name was Andrew and had great customer service.I will continue to buy Red Label Abrasive belts as customer service is big to me and people who stand behind their product are even more important.In regards to longevity, I’ll post an update in about a month or so as I have only sharpened a few blades however I haven’t had any issues so far.

Liked it had very corse all the way to 5000 grit
