I was trying to tighten the screw that holds the blade in place on my SOG Trident, and it looks like it stripped. I can stick an allen wrench in it, and it's still pretty snug. But the wrench will spin without the screw if I apply any torque. What should I do? I know that I can slot the screw with a Dremel cutting disk, but I'd rather not if I don't have to. Any thoughts? Thanks
