When Chuck created this section of the forum, he discussed getting members into DIY projects. If memory serves, I think three members went into polishing, one of them went professional.
I like to do EDC knives. Yeah, it's harder, and years of work have made bevels of differing widths, flat spots, rounded tips and chips. This is where you earn your pay.
Below is a client's knife that is only stone polished
The paper and glass will come later this afternoon, but if the client needed to run to work, the knife is ready now. Yeah, yeah, I know, I have to clean the ink, fingerprints and swarf off the tool, but it cuts, and the tip is pointy.
I can only echo Chuck's idea. Several of us will take a Kimber apart to find a flaw or broken spring--and we think nothing of it. The same ideal goes for knives, too.
In a few days when the client gets his knife back, it will be slicing, cutting and whittling dowels just like before. In other words, "working for a living."
