Chicken drill
Chicken drills are very effective weapons on sub-weight classes (like Antweights), they tend to get less and less effective though the more weight you are given to use though, at LW-level weight a FS would be a better choice than a drill for weaponry.
"Chicken drills" comes from Wicked Chicken, the first of this kind, and that is is basically a lightweight drill.
The original one is just a razor tip attached on an extender on a right angle. The razor and extender must be parallel to the right angle (just like a real drill)
You must make sure it isn't underpowered (on ants, you need a Nifty for powering the three RADs).
Spinning the weapons activates the chicken drill, that makes the razor spin at incredible speeds, much more than the right angle would normally give.
Chicken drills do good damage for their weight, and most importantly regular damage, on a class where it isn't easy to do actual damage on several bots.
Chicken drills can be used with Iron spikes on a Redbird too. You just need to have a weapon with a small diameter.
