My $40 Cabellas ones (that I've been waiting for years to break, but keep limping along) have screw-in tips that are replaceable. You can get metal or rubber tips. After years of using the metal ones (I think they are titanium), I realized it was dumb not to use the rubber ones. Much quieter with no loss of traction. I got several sets of each at one time a while ago. They were cheap. What you don't want to do is let the tips come out and find out later you've been hiking with the tapped receiver hole open. Cleaning that out is problematic. I would select for the screw ins.
