so i think I'm in the right place. looking through my stuff and i found a razor my dad gave me about 15 years ago. it appears to be unused and the blades all have this grease on it. can anyone tell me anything about this thing? is it worth keeping? if i wanted to use it how would i go about prepping it for use? id much prefer a Straight razor over this but i guess its worth a shot. any help is appreciated
