Mallets are often used to play instruments like the vibraphone and are very different from hammers used commonly to drive nails or cause blunt force trauma. While technically this implication works, I'd be hard pressed to think of a percussive mallet in the same scope as tool hammer or warhammer. Maybe further cleanup of both wikis is a better alternative?
Should I look through and try to populate mallet_(instrument) or does that fall more squarely under 'drumsticks'?
