The 6-inch slip joint pliers and 6-in-1 screwdriver are well designed.

Slip joint pliers are pliers whose pivot point or fulcrum can be moved to increase the size range of their jaws.

Most slip joint pliers use a mechanism that allows sliding the pivot point into one of several positions when the pliers are fully opened.

Straight slip joint pliers are configured similarly to common or lineman's pliers in that their jaws are in line with their handles.

There are many different varieties of slip joint pliers, including but not limited to straight slip joint pliers, tongue-and-groove pliers and lineman's pliers.

Get yourself a pair of needle nose pliers for small items, slip joint pliers for when you need a tight grip, and groove joint pliers for bigger jobs, like plumbing repairs.
