To get an as accurate as possible to the historical original, you need the thinnest blade you can get. Folks think his knife was a broken skinning knife. It would have had a kitchen thickness blade. When I was trying for very accurate Nessmuks I carried 1/8" or thinner.
Trying to get a mirror polished edge on this one. Almost there...
Sears believed in carrying a trio of tools, rather than some big heavy knife that was supposed to do everything. He carried a very small double bit hatchet, a belt knife with a thin blade, and a pocketknife. The blade shape excels at skinning and camp food prep. Its not a wonder knife for bushcrafting though. The back of the knife was supposed to be used to eat his potatoes like a spoon. His little book is a great read. You can download it on the net for free. Search for George Washington Sears.
I'm starting to think I want the minimuk, or stubymuk first because I want a new pocket edc blade. I'd use it a lot, and everyday. I think I'll get a campmuk, or a nessmuk at blade show this year [emoji41][emoji106]. So, help me out. Would it be too much to ask for in hand user shots of the little guys?
