Do you trust your girlfriend or wife? Implicitly? If you're going to let her own these, then you damn well better because she could slice your fat face up real nice and quick with these bad boys. OR she could give you a very pleasant back scratching... until she gets tired in 2 minutes.
Don't worry, we have the perfect solution to fight back. Strap on the Iron Reaver Finger Claw and fight to the death... of your relationship.
