It sharpened all the knifes in the house came with a good amount of belts haven't replaced them yet but I'm sure it's a thing to get the same size ones. Not extremely powerfully but it's not for that. It works for what it's for great

Love this sander! It's powerful, easy to use, and does an amazing job for sanding, grinding, and polishing. A real time-saver and a great addition to my toolkit!

Amazing! So powerful, smooth operation and surprisingly stable in the workbench! This tool is a must in any workshop, small yet a Giant, so please to own one!

It is very stable when used and can be used just by placing it on the desktop. , very convenient, and can automatically adjust the tightness, I like it very much.

My boyfriend loves it! Uses it for at home knife making. Comes with extra belts and grinding wheel. Great for fixing broken tips and adding a new edge.
