This black serrated Blur with a glass-breaker is crafted from a black DLC (Diamond-Like Carbon) coated Sandvik 14C28N stainless steel and a black anodized aluminum handle with Trac-Tec grip tape inserts. The Blur with a glass-breaker is equipped with SpeedSafe? assisted opening so you can easily open the knife one-handed. The recurve blade is built for multitasking with excellent slicing and piercing capabilities. This Blur also has a carbide tip built into those durable handles. And that?s important because a plain steel tip won?t have the same effect in an emergency. If you need to break out a windshield in order to pull a victim to freedom, it?s got to be carbide and the Blur glass-breaker, it is.
