The blade is spring-activated and retracts when lifted from the cutting surface, minimizing accidents and unwanted cuts. The powerful stainless-steel spring ensures blade tension on every cut. The durable ABS body has a textured design for a comfortable, non-slip grip. A sturdy stainless-steel support channel runs the length of the handle to support the blade for heavy-duty cutting.
