Knipex claims these cutters offer a perfect combination of cutting blade hardness and leverage (think handle length and shape) to cut with far less effort than other end cutters, which comes in handy when you’re cutting something bigger than bailing wire — like bolts, nails, or rivets.
Knipex’s website says the cutting surface is “forged from high grade, oil-hardened steel for maximum strength.” We assume they’re referring to the use of oil in the quenching phase of heat treatment. If you’d like to learn more about the process, there are some great Wikipedia entries on heat treatment and how it works that you’d enjoy reading.
We haven’t tested these pliers in person, but they caught our eye because in our experience it’s often concepts like this — matching a particular hardness to the tool’s design — that elevate a tool from average to extraordinary. Sadly, we almost never hear about the specifics because a) they’re trade secrets, and b) the marketing copywriters don’t understand what it all means anyway.
Certainly Knipex’s mention of “oil hardening” here isn’t an exception. Using oil in the quench process isn’t a rarity as far as we know; It’s just used to obtain certain hardnesses in certain metals because the oil offers different quench cooling properties than water, air, or other fluids.
Street pricing starts around $45.
