This Estwing hybrid hammer holder is made from a combination of 100% full grain cowhide leather and 1800D polyester. The wet formed leather hammer holder can adapt to your hammer for a perfect fit and behind the loop is a low-profile pocket that provides additional storage for a pair of pliers, utility knife, carpenter's pencil, or other small tool. Rivet-reinforced stress points and pocket corners add extra support to the binding edges to provide lifelong reliability. The integrated tunnel-style belt loop is wide enough to fit onto belts of up to 3-inches in width.
