Yes, we need more bladed weapons in game.
I guess sexy weapons are too much an opinion, so it is hard to think of things in this manner that would make sense for most people.
The whip of fangs would be an awesome addition for clerics of Lolth
There was also the claw bracer associated with the Cult of the Dragon, this maybe does not fit what you are looking for but photoshopped onto a picture of Minthara should make them sexy enough?
I want a +2 magic dildo please
In another game I play you can make a dildo spear, there is no magic however and the dildos are more useful to distract the npc enemies by throwing them (obviously won't work on players.)
