A combination wrench made of extremely high-strength cold drop forged CRV tool steel. The wrench has undergone a careful heat treatment process. It is hardened in a vacuum oven and quenched in oil to prevent decarburization on the surface of the wrench. It is then tempered at the right temperature, which reduces stresses arising during hardening and results in a significantly greater bending strength of the wrench.

Perfectly protected against corrosion by nickel plating and a matte satin coating.

The flat head set at an angle of 15° and the ring head bent by 15° make it easy to use the wrench and to unscrew fasteners in hard-to-reach places.
