Kershaw 5500 Collateral Assisted Opener Sometimes, innovation is what you dont see. For starters, the Collateral flipper stays hidden in the open position, creating a sleek, uninterrupted profile. This flipper takes advantage of both SpeedSafe assisted opening and KVT ball bearing washers, resulting in an extra-smooth deployment. With its D2 tool steel, the Collateral is no slouch in the cutting department, either. It stays secure during use with a frame lock. A carbon fiber insert adds a splash of class and contrast to the front handle. With so much to offer, the effectively beautiful Collateral is perfect for those who seek innovation.
