One of my straights is very loose and I find it very difficult to shave with.( It also opened up on me and cut me as I was moving it.) Is there any way to tighten a straight so it doesn't flop loosely from its housing?
Put one side of the pin on a solid anvil like surface. Gently tap the other side with a big heave spoon, or a very light hammer a dozen times. Flip it over and do the same thing to the other side. Check and repeat if necessary.
