Overview
Knipex names this cutter 78 81 125, and the 125 points to a roughly five-inch tool built for close, precise wire work rather than heavy cable. It weighs a light 0.13 pounds and carries a 4.7-star average across about 1,500 reviews.
Knipex typically names tools by their length in millimeters, which is where the five-inch estimate comes from. That size and weight class is one the brand commonly uses for electronics and fine-wire diagonal cutters, though this specific listing does not spell out a cutting capacity.
