I have a question. If you close the razor and turn it upside down will it open?
I ask because I saw the presta valve cap on the hinge holding the razor open. A tight pivot will stay open with all of my blades that actually are tight. Did you have any issues here? I know some people use a prop if there is one area of slip or as a safety measure and I didn't want to assume.

The restore looks great. Are you planning on putting up better pics at a later date? What are the scales made out of?
