Trying to attack that stuff with a hack saw is like taking a butter knife to a broom handle. Only a grinder will do it. Definitely a lot tougher than mild steel. Perhaps it has undergone a hardening process, I don't know, but from my understanding that is the way it comes. There is no doubt for me titanium will resist grooving better than regular bridge pins, which often seem to be little more than glorified nails. I might even worry about the string wire becoming grooved from the titanium pin :^) Having said that, there are numerous metals and alloys that are tougher than mild steel and might be candidates for bridge pins.
