    not tested, already broken

All measurements (3 more)+

Jaw limitation

  • 1Illinois Industrial Tool

    cutters don't extend inward to the pivot point, so the nail could not be placed all the way inward against the pivot point

  • 5DeWalt

    jaw opening is pretty limited, so the nail was too large to rest against the pivot point

How it was tested

  • squeezing force, measured in lb via a hydraulic press on the handle end, required to cut through a 16-penny nail
  • force required to cut through a deck screw
  • force required to cut through a 3/16 in drill bit (a durability/failure test)
  • force required to cut through or destroy a hardened socket adapter, beyond the tools' intended use (an extreme durability/failure test)
  • leverage geometry comparison: distance from axle/rivet center to the cutter opening, measured on select brands
  • weight comparison across all brands tested

If you're looking for the pliers that are going to last the longest, the Knipex brand is very well built and will probably last the longest, but it's very expensive and it takes more effort to make a cut. For that reason, I like pliers that offer a little bit more leverage, which includes the Irwin as well as the Channellocks and they are far less expensive at only 18 and 21 dollars respectively.

From the test video verdict.
