Great stuff, I also used to collect sheath knives, and still have them.
Something that I would like to have is one of the (not for public release) videos of the Bowie knife training that Bill Bagwell was giving to Army Special Forces, years ago.
Having one of his hand made versions of the Hell’s Belle would be nice also.
Our farrier is really good at knife forging, my wife gave me a fine Damascus blade made by him with a manzanita burl handle. It’s way cool and goes well with my pair of 1858 New Army Remingtons.
