Model 1-6" blued blade.
Made in the 60's. Seven spacer, ebony handle with nice flanged scalloped butt cap. The knife has seen some use and one of those you ask "if only they could talk". Blued blade not done by Randall and done after some sharpenings. You have to look close but there is a stamp or etch on the blade so no, it is not an unmarked blade. Comes in a model C style sheath that is marked 5-6" but this is a model 1. Very unique knife that I'm not overly sure I wanted to part with.
