Talking of knifes, I have a pair of knife issued to me in 1971 with the D of D Crows Foot on them, they where possibly 20 years old when I got them, new old stock and the are mild steel.
They are a pain to keep nice and shiny, but hold the best edge of any of the knives I have had since, yeah, I still have them, put away in a save place in there sheaths.
They are the original reason I started playing with leather.
