So one of my vintage blades does not stay open by itself. Its still centered and wiggles only a tiny tiny bit. Is there a way to make it stay open by itself or do i need to re pin to be able to make it stay open? (ive seen people just put pencils to keep them open for pictures) It does not bother my shave in anyway.. its just the only blade like that that i own. Once again thank you gentlemen.
