# Knipex High Leverage Diagonal Cutters (8")

## Why Knipex

Cheap diagonal cutters work fine on copper wire and zip ties. The moment you hit a hardened nail, a piece of piano wire, or ACSR cable, cheap cutters either fail to cut or the jaws chip. Then you buy another pair. And another.

The Knipex 8-inch high leverage diagonal cutters are $35\. They are made from chrome vanadium electric steel, hardened to handle materials that destroy lesser tools. You buy them once.

## What They Cut

- **Hardened nails:** Clean cuts, no jaw damage.
- **Piano wire:** Cuts without the wire slipping or the jaws spreading.
- **ACSR cable:** Aluminum conductor steel-reinforced cable. Most cutters cannot touch this.
- **Standard copper wire:** Obviously. Up to 0 AWG with effort.
- **Zip ties, cable sheathing, romex:** Effortless.

## The High Leverage Design

The pivot point is positioned closer to the cutting edge than standard diagonal cutters. This gives you roughly 20% more cutting force with the same hand effort. For all-day use or tough materials, that difference adds up.

## For DIYers

You might think $35 cutters are overkill for home use. They are not. Even if you only use them a few times a year, you will never have to replace them, and they will cut everything you throw at them without hesitation. That is worth more than saving $15 on a pair you will replace in two years.

The verdict

Cuts what others won’t.
