Bowblade and Violin Shield.

A working violin and bow, with the former mounted as a shield and the latter doubling as a sharp blade. Blade is STR+2 vs AC, 1d8+2 dmg. Shield is +1 to AC. Bards gain a +1 to the blade attack roll, but only when carried with the shield. Possession of the pair also grants a bard +1 to any remotely bard-related skill check.
