Hey guys actually a 2 part question,I have looked a bit and am not able to find out what kind of tool steel was used on the Gerber C325,seen one nugget that said that It may have been M2 ,but they weren't sure?

What kind of steel did Gerber use in their standard Sportsman folding knives,440c??
 
If memory serves, Gerber did use 440C in their Sportsmen Sporting knives. This would have been prior to the acquisition by Fiskars.

Gerber used M2 on knives, yours included. 440C was the base premium steel on the Sportsman line. They also used L6 for a while ( Mk 2 and ?) as well as Vascowear on the Sportsman 2 "V" steel option for a while. They made a company knife for Vasco pacific, the maker of Vascowear using that steel in the Sportsman 2 and made a run of plain models just stamped "V" steel for a couple years during the early 80's. Later they also used ATS 34/154cm, S30V, and 420hc
 
I have a set of Gerber Miming knives from 1947. Any idea of the tool steel used back then? They aren't the the later chrome-plated version (which I also have, which I believe is M2 steel).

not sure about the 1947 version but the later stuff was M2,I know they had M2 steel in the forties but I don't know when they decided to chrome plate the stuff

Been getting into some of the old stuff lately,I had never heard of miming knives and at cutlers cove they have an article on them and have all the old advertising material and it shows they used high speed tool steel of which M2 is about the only hs steel used for cutlery at that time (nowadays of course we have m4 which is considered an improvement)-they even showed the elements breakdown and it is indeed M2 steel,so it looks like these should have some great edge retention .
