Mine was from a Haward razor.
It's amazing how a faulty SR can self-correct its faults over time .Cut myself regularly with my Dorko SR when I first got it about 30 yrs ago. That was not fun. The razor is fine now…never cuts me.
I was razor cutting a client's hair, removing some bulk, and decided to remove the razor guard and WIPE THE BLADE OFF with my thumb. Yeah, it was as dumb as it sounds.This here true story is gonna take me awhile to tell properly, so I will tell it when I am more awake!
