After my near-screed on overlabeled new razors, I remembered a question I've had for a while about new TIs. The main reason I'm interested in trying out a TI is their old lead-hardening process. I'd just like to try out a piece of steel that's been treated that way. But if I buy a TI with a Sheffield blade, am I getting that same process? Does anybody know if they buy Sheffield blanks then harden them the TI way, or do they just grind them and put them in TI scales?
