CYRO-TREATING ?

[po boy]

I was looking at geting a Randall Knife and in reading I cannot find any mention of deep freezing as part of their tempering process.
If a knife is hand forged does it not require this treatment to toughen it for extreams thanks for any info

Hand forging and cryo treating aren't directly related with each other, it depends on the steels you're using as to whether or not cryo is beneficial. Generally, anything with a lot of chrome (ie stainless) gets the most benefit from cryo treating. I've also found that there are some ways around that, but that's up to the judgement of the heat treater. Did the site you saw mention what steel was being used?
