The IRWIN® VISE-GRIP Original Locking Sheet Metal Tool, 8", makes bending, forming, and crimping sheet metal easier than ever. Constructed of high-grade heat-treated alloy steel for maximum toughness and durability, this metal bender also features the original locking mechanism that made VISE-GRIP famous.
