A2 tool steel and Dry Ice?

[BallewBlade]

Just a random thought, Im going to be making my first A2 blade and I know its an air hardening steel and that cryo treating it is the way to go. Do you guys think I could get close to a cryo treatment with dry ice? If so how would I go about it? Has anyone done this before? I searched this site and could not find any solid info. Thanks

Dry ice will be fine to do the sub-zero part of the quench. A-2 isn't all that complex.
