>>5223834Huh, in that case how about a twinblade/polearm? One head for the Flamebringer, the other for the rapier. The bones and mucus can be used for the handle.
It's definitely more difficult to use than a regular blade - we might need a trainer - but it's simple enough to work with that the end result won't look like a switch weapon (the smith will get more breathing). It's also sufficiently stylish.
