The IRWIN VISE-GRIP 6-inch V-Jaw GrooveLock Pliers are quick-adjusting tongue-and-groove pliers designed for versatile gripping on round, hex, square, and flat surfaces.

It is best suited for DIYers, plumbers, and mechanics needing quick, precise gripping for pipes and fittings.

The Klein Tools 38610 is a 4-inch long nose locking plier designed for secure gripping in confined spaces, featuring a slim head and high locking force.

Ideal for electrical work and plumbing in tight spaces, though it is not insulated for live circuits.
