Combination spanner made from extremely durable CRV tool steel, cold die-forged. The spanner undergoes a careful heat treatment process. It is hardened in a vacuum furnace and oil-quenched, which prevents carburization and burning on the spanner surface. It is then tempered at the appropriate temperature, which reduces stresses formed during hardening, resulting in significantly greater bending strength of the spanner.

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

Flat jaw set at a 15° angle and box end bent by 15° facilitate maneuvering the spanner and loosening fasteners in hard-to-reach places.
