I use hand engravers- hammer and chisel also. I also nade an engraver from a tire compressor that mimics the energy from an engraving hanmer- it has a piston inside the handpiece and its mobile. The gravers are sharpened carbide and hss steel sharpened to with a 105 degree template.
I hope so! There are fewer carvers than there were a few years ago! I collect also and I hope more people start carving them!
