Not intending this bit to serve as a metal detector, but I managed to use it for that purpose! It worked very well on 60 y/o yellow pine framing lumber prior to filling it.
I found one video on sharpening, but am curious of any other options or suggestions on round stones. The video seems to suggest grinding the edges off of a rectangular stone while I’m finding stones that are already rounded.
