Worth Keeping on Hand — Great Performance and Long Lasting
If you’re running the Ken Onion Blade Grinder Attachment, these replacement belts are absolutely worth keeping around. The quality is noticeably better than generic belts, and they do a really good job of cutting consistently without heating the blade up too much. The progression of grits works well, and the 12,000 grit finishing belt can leave a seriously refined edge if your technique is good. I’ve been able to get knives to a true hair-whittling sharp edge with this system, especially when paired with the Blade Grinder attachment and proper belt progression. The factory belts are designed specifically for the system and seem to give more predictable results than trying to cheap out with off-brand options. The kit includes five 1" × 18" belts with grits ranging from extra coarse through ultra-fine polishing. One thing I’ve learned: once you get comfortable with the Blade Grinder attachment, it’s hard to go back to guided systems because this is simply faster and more consistent for getting an extremely sharp edge. That said, belt life will depend a lot on steel type and how aggressive you are — if you’re reprofiling hard steels, expect to go through coarse belts quicker. My only regret is not buying into the system sooner. If you already own the Ken Onion setup, these are basically a no-brainer consumable to keep on the shelf.

It has the belts I need and they sharpen knives
I only sharpen my own knives. And the belts lasts for me. I have not worn them out , but I question how long they will last. Belts are consumables.

Awesome
Awesome product. Great sharpener. Family owned and operated and getting bigger and bigger. Love to see it. Keep them coming. Great price and one of the quickest easiest sharpeners to get a mirror edge on.

Great replacement belts
If you sharpen common household stainless steel knives or standard carbon steel blades, these belts last a good amount of time. It's only if you are doing high end particle metallurgy steels that these belts will naturally wear. But otherwise great belts!

Great belts….
To be fair if you have one of these mini bench grinders then you already know how good they are and that there aren’t really any other options for this machine so a review seems unnecessary…however they are good belts. Watch for price highs and lows, seen these from £21 - £35 plus so hunt about, oh and our silly government think a belt sander is only for knives so you have to be in to revive this item which consists of sandpaper!! U.K. going mad
