What is this cutter specifically designed for?

This precision cutter is designed for ultra fine electronics work and safely opening or cutting plastic cable ties on wire harnesses.

What cutting capacities does the Knipex 79 02 125 S1 offer?

It cuts soft wire from 0.2 to 1.7 mm, medium hard wire up to 1.3 mm, and hard wire up to 0.7 mm in diameter.

Why are the edges on the head rounded?

The rounded outer edges reduce the risk of damaging conductor insulation when working on dense cable harnesses.

Is this diagonal cutter insulated or non-sparking?

No, this cutter is not non-sparking and not insulated for work on live circuits. Always turn off power before use.

What advantage does the bolted joint provide?

The bolted joint ensures zero play, low-friction operation, and permanently precise alignment across repeated cuts.
