This design is apparently still under patent, so there are no cheap imitations. Unlike all other slip joint pliers, they have a cam mechanism that keeps the jaws exactly parallel at all times, earning them their name: pliers wrench. Nick swears by his $50 pair. |
This high-quality slip joint plier is made for electricians. The funny angle tips at the ends of the handles can be used to knock out the pre-punched holes in electrical boxes, and the hard square corners on the jaws can reem them out to smooth the edges. |
These slip joint pliers have jaws that grip four of the six sides of a hexagonal nut. The package even shows them being used on a nut, to reassure you that this is an OK thing to do. |

This modern contraption is a better-made, and more useful version of a combination pliers and crescent wrench. For one thing, the pliers lock shut, so they stay out of the way when using the wrench. It also has a knife and screwdriver set built in, and it’s pocket-sized. In other words, it’s a multi-tool with heavy emphasis on pliers and wrench. |

This is an old (patented 1916) take on a sliding, parallel jaw pliers, named the Plierench by its inventor. You can adjust to different size ranges by opening the handles wide and sliding the jaws. |
These don’t work well either. |
These things don’t work. They try to automatically slide until the jaws start pressing down, and then switch to pivoting so you can apply pressure. In theory, great, in practice, terrible. |
I guess that’s one way to make a pair of pliers that also works as a wrench. |

With these you push a spring-loaded button to release the joint to slide to a new position. |

This style of slip joint pliers have to be opened beyond a certain point to allow the joint to move to a different notch. When closed, a curved tongue-and-groove keeps the pivot point in position. |
This variation is much more common than the double-crescent-wrench style. I mean, who could doubt the usefulness of having both pliers and a crescent wrench in one? Anyone who’s tried to use one of these, that’s who. |
