Customer Reviews (4.6 / 5 · 5 reviews)

Harper C. ★★★★★

I grabbed these to refresh some old chisels, and the 1/2" width works perfectly on my knife jig without jumping off the platen. They cut fast but leave a nice even scratch pattern—much better than standard belts.

Madison ★★★★★

The pyramid abrasive structure on these belts cuts much more consistently than standard sandpaper, and they hold up noticeably longer on my knife edges. Really smooth finish after just a few passes.

Henry ★★★★★

Finally gave these a try after using standard belts for years — the difference in edge finish is night and day. Wore one belt through three knife sets and it still cuts cleanly.
