Emporer Jr. Black Titanium and Rhodium with the M3 Damascus Steel blank. Was a blast to make. After it was completely done, I read that I needed to have on the mask. I had on three surgery lapsponges.... Both myself and the surgeon that were in the shop had some problem the next day during surgery. "Gosh, my head hurts...." Sinuses were flarred up big time. WEAR THE APPROPRIATE MASK for this blank folks.
