Description

SILENTE is unique in its kind and it performs unique needs:

the handle is crafted in two parts and it works also as the grip of a clamp placed at the end of the handle itself.

Besides taking hold of everything that has the appropriate dimensions, the clamp can be used to cut wire-fences, wire-rods, steel cables, etc. and it can be used as a glass breaker thanks to the tungsten carbide insert placed at its end.

The sheath protects the cutting part while using the clamp in safety, but it can also release the blade with a retention system that can be activated quickly and silently.

It can be fastened at thigh or on M.O.L.L.E. system. It is integrated into the operator's equipment using minimum space.
