I got these three rods of HSS at the flea market, leftovers from a long gone industry. I could not find others for sale, not even online, so I decided to make the most out of them by sharpening at both ends, so I can get more tool profiles this way.

This required a handle that allows for easy flip of the tool, so I'm making one in this video. It also allows for the tool length to be adjusted, so the chisels can be long like those used on the lathe or short, for engraving. I also added a brass end cap so I can tap it with a hammer when engraving metal.
