Thread: Razor wont close?

Jimmy could be right.

My theory was to do with the way the tang tapers and the scales bow to create friction on the pivot. If overtightened, sometimes those factors combine to force the blade open a bit - only maybe 5 degrees or so. Expansion (I would guess of the scales, but I suppose it could also be the metal) would increase the tension and make the popping open more likely. Since pivots loosen a bit on their own (and the bone may wear a bit), this should go away in the future. Or if you do a final rinse under cold water or avoid getting hot water on the pivot, you may never have the issue again.
