Hi
If you can still find them, I'd start with a Russel Green River knife of some sort. Jantz in Oklahoma is out of many styles, but still have a few. These are slab sided basic blades. Also check Crazy Crow and Track of the Wolf. I"ve purchased from all three.
If you have a drill press, or can drill straight down without one, and have a belt sander, c clamps, and epoxy, you're ready to go.
