Looking for some info on cryo treating along with temper cycles as it pertains to dewars. How large should one be if only treating folder blades? How long does a standard dewar hold nitrogen? How do you use the thing....suspend blade on a wire and drop down into nitrogen? Any wire? Thanks

I have a 25 litre and usually have it filled half full costs me 20 bucks at the local welders supply,It will hold this for about 4-5 weeks.
I suspend my blades on 1/16" SS welding rods I get from the same place.They have no flux on them and 36" long. Makes great pins for handes too.
