It’s a slightly modified belt sander from harbor freight. 1x30. You can find good belts online for them. If you need some message me I’ll give you a link to some
I wouldn’t sharpen on a grinder. Get a high quality resin bonded diamond stone. Your edge will stay sharper longer. Those aluminum oxide belts tear the carbines right outs your edge. Not to mention the heat you build up on the surface going that fast. I’m sure someone will say well that’s how they sharpen at factory…n that’s by the blades never straight. Ever blade usually comes revive at the plunge line. I always end up fixing it starting from 120 working my way to 2000
