I found this old NYKC knife on an open air antique market in my home town on the bottom of a cardboard box filled with worn out junk knives, and it was inside the blue leather pouch also in the pics, which most likely kept the wood well protected.
Paid the massive amount of 10 Euro for it.
The steel grinds & sharpens quite easy, comparable to most 1095 steel, but it keeps a keener edge for longer.
