I have started making a couple of folders. The smaller one is going tobe a friction folder and will have bone scales on blue steel liners and a 3" scandi grind blade.
The larger one is going to be a copy of a Colonial pocket knife from circa 1650/1790, and will have a external spring lock back. I found the design in Fur Trade Cutlery Sketchbook, by James A Hanson. I am going to make this one as close to the drawings as I can get it. It's a going to be a beast, 10" open, 5 3/4" closed. Maybe they had big pockets! or more likely kept it in a bag. It has a convex grind, again as close to the sketches as I can get it. The handle is going to be horn, just waiting for it to arrive. The spring is going to be a bit more of a challenge to make as I haven't made one yet.
The author says that all the knives sketched in his book are in the Museum of the Fur Trade in Chadron, Nebraska, so should be authentic artifacts rather than "outlandish cheese knives and toad stabbers" people keep showing him as authentic reproductions and exacts copies...His words...!
