Raptor blade, new exotic weapon

[Aries]

This new weapon and the feats are heavily inpsired by WH40k. The inspiration was taken from this picture: http://www.eldaronline.com/images/pa...eeexarch01.jpg

Basically, a Raptor blade is the exotic version of an armor spike. It is attached to either the forearm or the elbow is the shape of a curved dagger.

The stats of the weapon are similar to an armor spike: 1d6 , 20 x2.

The difference is that a character can take the following feat:

Improved Raptor Blade fighting:
Req: Exotic weapon proficiency: Raptor Blade, +4 BAB, Ambidex, and two-weapon fighting.
Benefit: a character with the Improved Raptor Blade fighting style can use the raptor blade in combat in addition to the other weapon he/she uses. That is, a character can freely attack with the weapon in his hand, as well as the raptor blade. The character will receive a -2 penalty to the attacks with both weapons, and the wepaon must be light.

I realize that this weapon can be hugely exploited be character with sneak attacks, as a character with two short swords and a raptor blade, could potentially make three sneank attacks in a round. But the price would be two feats, as well as the fact that it is an exotic weapon so access to enchanted Raptor blades are limited
