A good thing to know is that back in the medieval times, every single part of a weapon was considered to be a weapon, if you sword stab failed, nothing stopped you to use the piece that protects your hand (forgot it's name) to pierce your opponents eye using the motion of your failed stab.

It's not like the blade itself is the only dangerous part of the weapon, so it's no surprise that when someone see a part that can conveniently be used to do damage, they use it and use it we'll :3

(And your wings are neat, far better than theirs x3)
