This vintage Edge Mark Folding Hunter is built like a tank. It has a 3.5" cutting edge of 440 stainless steel sandwiched between two solid slabs of stainless steel which are clothed in rubberized checkered scales. The pronounced finger choil coupled with a similarly pronounced thumb ramp allow for some real up close and personal controlled cutting. This knife was made in Japan and I'm guessing around the 70's or 80's? If anyone has any information about this knife I would love to hear it. I have never seen one quite like it. It's a really solid, hefty piece that was built for hard use. You can gauge its size by viewing it posed next to the brown Spyderco Paramilitary 2 in a couple of the pics I've uploaded.
