The Battle Rat, Howling Rat and Mudder handles won't work on a sword.

If a new handle mold is going to be made, I vote for ridges like a mudder without any palm swells.

I think a two hand grip is critical. With a Resiprene-C handle they need to add weight to the tang for ballance. An exposed Pommel would be nice. A steel bolt on pommel cap/weight might be better.

A fuller in the blade would look very cool and help with ballance.
