The Knipex Electronic Super Knips XL (78 03 140) is a professional-grade cutting tool engineered for technicians, electronics hobbyists, and fine mechanics who require extreme precision. Its primary benefit is the ultra-fine, bevel-free cutting edge that delivers perfectly flush cuts on wires as thin as 0.2mm, though users should be mindful that these high-precision edges are intended specifically for soft and medium-hard wires, not for heavy-duty steel or hardened materials.

No. These pliers are designed for soft and medium-hard wire. Cutting hard materials like piano wire will damage the precision-ground edges.
Bevel-free means the cutting edges meet flush at the tip, allowing you to cut a wire entirely flat against a surface without leaving a protruding 'nib' or tail.
The standard version of the 78 03 140 is not explicitly marked as ESD-safe. If your application requires full electrostatic discharge protection, check for Knipex models specifically labeled with ESD-safe properties.
These pliers are precision-ground at the factory. Attempting to sharpen them yourself may ruin the micro-misalignment and the flush-cutting capability. It is recommended not to sharpen them.
Knipex offers various sizes in the Electronic Super Knips series, such as the 125mm model, which is more compact for very tight, delicate spaces.
Ensure no debris is lodged in the rivet. Apply a drop of light machine oil to the joint and operate the tool several times to distribute it.
Check the cutting edges for nicks. If the edges are damaged, the tool may have been used on materials harder than its rated capacity. Ensure you are only using it for soft or medium-hard wires.
Verify that the opening spring is correctly seated and that there is no obstruction inside the handle cavity preventing full opening.
No complex setup is required; the tool is ready for use immediately out of the packaging. When using the pliers, ensure you are cutting within the rated capacities of 0.2-2.1mm for soft wire and up to 1.2mm for medium-hard wire. Attempting to cut materials exceeding these specifications, such as steel wire or thick copper busbars, can chip the delicate, precision-ground cutting edges. For maintenance, keep the rivet area clean of debris. If the movement becomes stiff after exposure to dust or chemicals, a small drop of machine oil at the rivet joint will restore smooth action. Store the tool in a dry environment to maintain the integrity of the INOX finish.
