I just recently finished some S35VN blanks. HT was foil wrapped in 309, throw in warmed kiln that's been at 1550 for 30 minutes and let sit for 10, ramp to 1975 hold for 25m, plate quench with compressed air, into -100 dry ice slurry for 1 hour, temper at 375 for 2hr X2.
I then started to hand sand a finish on them, decided to try one of them in the blast booth of sieve 3 glass and after blasting one side I took it out and noticed it went from perfectly straight to a banana.. freaked out a minute then blasted the opposite side and the blade curved back.. kinda wonky straight but mostly straight.
Anyone know what happened? Thanks
