I was just wondering the other day it if would be possible to use rithmatics to make what would basically be an invisible sword.
Sounds a tad strange, but hear me out.
Say you had two pieces of wood arranged in a "T" shape. If a Rithmatist drew a line of forbiddance on the top of the T, wouldn't it create an invisible plane out from it? And, doing to the small nature of the item, it would be simple to move it around, therefore changing the location of the invisible plane. While it may not cut like a sword can, it would be an easy to use bludgeoning weapon.
So, what do you think? Are there any obvious errors in my logic? Would anyone actually do this in the United Isles? And would a person be able to push the plane, seeing as it isn't rooted in a sturdy floor or wall?
