The low wear riveted lap joint design is able to withstand high levels of load. Wiha's DynamicJoint gives the most efficient transmission of hand strength to the cutting edges. The advantage results in 40% less effort being required for cutting tasks. This gives a lightweight action feel, whilst clean cutting is achieved by specially milled precision cutting edges. Additional inductive hardening to 64 HRC enables the cutting of piano wire. Individually tested protective insulation 1,000V AC, VDE and GS tested.
