What type of steel?

I have this Case made C. Platt & Sons Commemorative muskrat that has a three line tang stamp on one of the blades that reads "C. Platt & Sons' above "Elred, Pa." above "XXXX". On the other blade, it reads "USA" above "Muskrat" above "SS".

Can anyone tell me what type of stainless Case used to make these knives?

It would appear to my novice eye to be a well made knife, The finish is superb and the bone scales are very nice. It was "scary sharp" right out of the box.

Thanks for any information on this knife.

hey I am not an expert on this case knife, but if memory serves me, this is the same type of stainless that case uses on all their knives except for the tony bose editions and the new tested red bone series

hope this helps

I am also not quite sure due to the names Case gives their steels. I believe it is a variant of 420 ss. 420 steels are available in sheets (maybe even rolled) , so they can stamp out a bunch of blades at once. Because of this, I often refer to it as cookie cutter steel, even though it is a fairly decent steel. Vandium is added to some, likely .25% or less to make a tougher steel. This creates Vanadium carbides as well as the chromium carbides that are normally in stainless steel.

Case CV is carbon steel with both chromium (per centage not enough to qualify as stainless) and Vandium added for toughness.

Sorry, I can't help you more, due to the names Case uses, it's hard to say exactly what they are unless you are a die hard Case collector, I just have a few.

Case uses enough blade steel that they can probably custom order their own proprietary steels directly from the mill. Just a thought there.
