Wiha’s BiCut tools are diagonal cutters with a twist – or should I say a button. These odd-looking pliers feature an innovative “power” button that shifts the tool from its regular cutting mode to a higher power cutting mode, and back.
From the looks of it (watch the video below to get a better sense of how the power function works), the power button shifts the cutter’s pivot angle to reduce cutting effort.
It almost looks as though the power button engages a compound leverage mechanism, but there doesn’t seem like there would be room for this in the cutter head. Instead, it looks like there are two different pivot positions, with the higher power cutting mode causing the handles to spread a little further apart than in the standard mode.
With these Wiha BiCut cutters, you get regular operation for most tasks, and engage the higher leverage mode when you need it. This way you get the benefit of the heavier duty cutting performance without having to deal with wider-spreading handles for applications where you don’t need extra power.
There are 4 models, all are 8″ (200 mm) long:
- BiCut Professional (Z 18 0 05)
- BiCut Professional Electric, which is insulated with 1000V-rated protection (Z 18 0 06)
- BiCut Industrial (Z 18 0 02)
- BiCut Classic with dipped handles (Z 18 0 01)
The Professional, Professional Electric, and Industrial models all have cushion grip handles. It’s not really clear what the difference is between Professional and Industrial models – any ideas?
Wiha says that the power mode allows the BiCut cutters to do the job with up to 50% less hand strength. In other words, the power mode essentially doubles the cutting force for when working with harder materials that are tough to cut.
The blades are induction hardened to 64 HRC, and can cut wires, cables, nails, screws, wire cable, spring wire, chains, and other similar materials. All of the BiCut cutters are made from C70 tool steel.
Additionally, the cutters feature Wiha’s DynamicJoint blade profile, where one blade is 50% thicker than the other (60% and 40% ratios), for an additional reduction in cutting effort (up to 40%).
Right now, the Classic style Wiha BiCut cutter is available via Amazon for $40 and is listed as usually ships within 3 to 4 weeks. The cushion grip Professional and Industrial models don’t seem to be available anywhere in the USA yet,
It’s difficult to say without further insight into how the Wiha BiCut cutter heads works when in power mode, but the new cutters look to be better than other high leverage cutter models that have come out in recent years, such as the Knipex TwinForce. By better, I mean capable of cutting regular or hard materials in a single operation with minimal fiddling, and cheaper too.
