... do you have any thoughts about handles with facets (think something like an octagonal cross-section), to help with preventing rotational twist? Instinct suggests it would, but would such a handle cross-section be likely to cause blistering with the swinging action involved?
No idea. Tennis racquets are bevelled but have a leather or towelling wrap on them. Somehow, I can't see our knife nuts going for this option though
