The CAC® knife is the third version of the "campaign knife" designed and manufactured by TB for the French Army in collaboration with Phlippe Perotti, former special forces and expert in the handling of firearms and knives. Much more technical and ambitious than its predecessors, the CAC, with its uncompromising design, light weight and robustness is TB's response to the demand expressed by the French army, namely, to design a rugged and secure knife whose opening and closing are done with one hand only . The mechanism is extremely resistant and ensures a flawless blade lock in the open position. The weight is also optimised in order to get the strongest and lightest knife possible.
