With Wiha BiCut pliers, you get two tools in one. These pliers are a combination of standard diagonal cutter and high-leverage cutter. Switching between one and the other is a simple matter of pushing a button on the cutting head. Pushing the button to change into the high-leverage mode effectively doubles the cutting power, reducing effort by 50%. For cutting softer materials such as copper wire, use the standard mode. For hard, such as cables, nails, screws, bolts, wire cable, spring wire, chains, etc. switch to high-leverage. The pliers are drop forged, high quality C70 steel, hardened to 64 HRC. These VDE pliers are suitable for all work on or around electrical components up to 1,000V AC, each individually tested at 10,000V AC. VDE and GS tested, DIN ISO 5749, manufactured according to IEC 60900:2004.
