I found a nice razor at a local antique shop. The blade is in pretty good shape, but the pins are way too loose for my liking. I'm still pretty much a noob when it comes to shaving and I've never even attempted to restore anything (beyond simple polishing) yet, so allow me to ask what is no doubt a silly and obvious question to most of you:

Short of cutting the pins and re-pinning a razor, is there any way to tighten up the pins so the razor doesn't open and close too easily? I'd feel way more comfortable with a razor less prone to unintentional slippage.
