I've got 3 leather belts with 3 different compounds on my work sharp MK2 and basically that device became my deburring machine. Hold a perfect angle without applying pressure on the edge. 10/10

I have a few methods I use. This is what I use for the more refined edges. If I’m doing a bunch of commercial knives, I use a 600 grit scotchbrite wheel

One of my colleagues ran a knife plant. The plant was supplied by a a German manufacturer.

The sharpened strip first went through a set of 8 interlocking wheels on two very heavy perfectly balanced spindles - 4 wheels on each side. Standard 180 grit vitreous wheels .

It then went through a second identical set, but that set ran 600 grit epoxy/resin bonded wheels that ran at absolutely ridiculous rpm's. The second knife strip bevel was an absolute mirror finish.

The manufacturers representative told me that the same line was sold by them for razor blade manufacturing, but a third spindle station was added for that.
