Overview
This Irwin diagonal cutting plier has a built-in spring and an alloy steel handle, weighing 4.96 ounces. The spring pushes the jaws back open after each cut instead of leaving that to your hand.
The name says most of it: standard diagonal cutters with a spring added, alloy steel handle, under 5 ounces total. That is a tool built for repetition rather than one-off heavy cuts, and it carries a 4.7 rating across 3,631 ratings.

Who it's for
Electrical work, wiring, or crafting where you are making many small cuts in a row and want the jaws to reopen on their own. Not the choice for cutting thick or hardened wire that calls for a heavier, longer-handled cutter.
Strengths and trade-offs
Drawn from this product's published specifications.
- Spring loaded jaws speed repeat cuts
- Light under 5 ounce weight
- Alloy steel handle
- No blade length or wire gauge listed
- Light build may not suit heavy cable
Performance notes
The spring reopens the jaws after every cut, so your hand only has to close them, which speeds up repetitive work compared to a plier you have to reopen manually each time. The alloy steel handle keeps total weight under 5 ounces, easing fatigue over a long session.
