Liq. N2...so what if I.....?
Here is a question for you guys!
What, if any effect would placing an old (late1800's) razor in liquid nitrogen do? Would it help the hardness, would I risk cracking the blade, just make the blade VERY cold, etc...?
Also, if I were to try this would you recommend a slow progression to the temperature differences and then a slow progression out?
(e.g. 4 C, -20 C, -80 C, -140 C, Lq N2, -140 C, -80 C, -20 C, 4 C, Rt)
I'm not too familiar with cryo-tempering of metal and am thinking of 'tinkering' with a blade I have been putting 'through the ringer'......
