Thanks ya'all, here is a image after slotting, the slotting saw, 3/32" thick, was re filed for improved cutting, the front edge has a 4" radius in it, 8" belt grinder, and is used to groove the slot. It cuts a chip on the pull or push. it removes a chip about .001" or less in thickness.
The small tool is about 1/16" wide and is used to remove antler from the blade end (closed) of the antler. It's amazing what a single point tool can do. They are used after the antler saw has established a groove. Once in a while the saw is used to go back in and true up the slot.
This project will be quite a while to complete. I talked to Gary, my son today. We may get together next week for step two, making a Mt. Man folder. I have a hunk of damascus steel stashed from a long time ago, maybe we do a damascus blade.
Mean while, I gotta get a batch of house hooks to Montana.
