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 WORKPRO 4-inch Mini Curved Jaw Vice Grips are compact locking pliers crafted from heat-treated chromium-vanadium steel, designed for gripping and clamping in tight spaces. They feature an integrated wire cutter and adjustable screw, though their small size limits leverage and jaw capacity. They are best suited for DIY enthusiasts and hobbyists needing compact tools for automotive repairs or jewelry making.
