Titanium hammer manufacturing

I need to get my hands on a titanium hammer. I can't quite wrap my head around the 'but it hits just as hard' part of the design. Yeah, I get that a lower mass object would be easier to accelerate, but I would think that the lower mass object - the titanium hammer - wouldn't deliver nearly the same amount of force.

I love seeing the various steps involved in the manufacturing process here, though. It's gorgeous to see each step along the way - especially the investment casting. Gorgeous.

Has anybody out there actually gotten to use a titanium hammer? If so, wanna give a report?
