This mechanism requires that part of the frame is folded inwards, firmly fixing the blade in the open position, increasing the operator's safety when using the knife.

On the tang there is a slot for inserting a lanyard, on the right side of the handle there is a steel clip that allows concealed carry in the pocket.

The blade is sheep foot shaped and has a small slot on the top to facilitate opening. Its particular structure, thanks to the straight edge, allows the user to comfortably rest his fingers on the back of the knife and use it with ease.

This version is equipped with a specific toothing that allows it to cut rope and even high tenacity aramid materials. This model is also equipped with a tapered shank which acts as an emergency screwdriver. Ant Rescue was developed according to the needs expressed by the "Alpine Troop School of the Italian Army".
