A lightweight and perfectly balanced tool. Create uniform inside corners on drywall with this tool. The blade is formed from flexible stainless steel so it will not rust or pit. The 103 degree angle flexes with pressure against the wall to a 90 degree angle when used. The 5" x 4" blade is 4" at the center and extends out 5" for full coverage to create corners. Reinforced blade supplies support for smooth inside corners and allows tool to keep its shape with extended use. Reinforcement is welded to blade for strength, and allows for the optimal amount of give. A smooth wood handle is attached with a metal ferrule. The contoured shape allows for a comfortable grip. A hang hole in the handle allows for easy storage. Proudly made in the USA.
