You know, an angle grinder is naturally pretty dangerous, but maybe combine it with a rotary saw of some kind? Serrated edges along with the abrasive surface allows more options in combat.

I had a thought which is why i popped in here. PEople are obsessed with sword bows, but I've never seen a staff of spear bow despite those easily being better weapons for combining with a bow.
