IRWIN

IRWIN is a professional-grade hand-tool brand with roots in the VISE-GRIP locking pliers line invented in DeWitt, Nebraska in 1924. The brand covers pliers, saws, drill bits, chisels, and fasteners sold under the IRWIN and VISE-GRIP names. IRWIN is a subsidiary of Stanley Black & Decker, the world's largest tool manufacturer, and backs its hand-tool line with a lifetime guarantee.

VISE-GRIP GrooveLock pliers are IRWIN's groove-joint (Channellock-style) line, distinguished by a Press-n-Slide button adjustment mechanism that allows single-hand jaw width changes without disassembly. The line is manufactured in a range of sizes from 6 to 12 inches and is backed by the full IRWIN lifetime guarantee.
