Hello wise members of straight razor place, i have a question in regards to a strange first time shave of a Joh Engstrom 5/8 frameback. The razor glides across with no problem, but when ever i past my nose i smell "burnt hair". I put the razor down and smelled my hands, and they smell like burnt hair. So i washed them off and continued after i completed one of the better 3 pass shaves of my life, the smell was on my hands again. i Finally grabbed the razor and smell the scales. The smell was coming from the scales i tried to wash them but they changed into a dark shade of green. I am guessing the scales are black celluloid scales with a lead spacer. They are in horrible condition and i was playing to either have them repaired or replaced. Has anybody encountered this and does anyone have a suggestion.
