Green, making a projectile or cutting weapon vibrate is just as absurd in its nature as putting a 6 pound weight on an arrow and saying that this will improve its penetrative capability by increasing the arrows momentum. It could indeed increase the momentum, but only if the arrow was actualy capable of accelerating to the same speeds with this gear, which it cant, and if the weight wouldn't impede the arrows aerodynamic properties, which it does.

Now look at mine and Guru's arguments, and you will see that this comparison is no hyperbole, oscillating bullets and swords being just as absurd as an arrow with a weight.
