1961 USGI Imperial non-magnetic UDT knife.. Came across this looking for a scabbard the other day and since Imperial was just being discussed,, I thought you guys might like to see another of their odd-ball military knifes.
Cheers, yv

What is the blade made of?

made in 1961 by the Imperial Knife Company under contract to the US Navy specifically for Divers working with or around magnetically detonated underwater mines like the MK56. This knife is made of Haynes Alloy no. 25 which is a copper-chromium-tungsten-nickel alloy similar to Stellite. It is non-magnetic, non-sparking and non-rusting even in seawater, yet unlike many other non-ferrous metals like the titanium used in Mission Knives it has the ability to be hardened to allow it to hold a cutting edge with a Rockwell C scale value of 53 to 54 which is per the final Naval specification.
