Titanium is tough, but it is not hard. after some use, it will start to mushroom, Unless it is alloyed with another material. Then its not titanium, but a Ti alloy.
We made some 600.00 hammers for the military back in the 80's. They were made from non sparking alloys, machined out of solid, environmentally tested, EM tested, certified, etc. they were for use in ICBM Silo's.
Nothing like banging on a 20 Kiloton warhead with a Hammer to clean out your system.
