TCG toothing enables pre-cutting over a width that is smaller than the definitive width. Avoids splinters in fragile materials. TCG-N toothing relieves cutting effort. Thus, the risk of kickback during the attack are reduced, and safety improved. Expansion slots allow the metal to expand when it heats as a result of friction, thus avoiding the deformation of the blade. Anti-kickback heel limits the quantity of material removed by each tooth of the blade. Thus prevents excessive cutting effort and eliminates wood emissions.
