Achieve a master-class finish with the Hyde Pro Stainless 6" Flexible Joint Knife.
The Hyde 06878 is built for the professional who wants a rust-free tool and a predictable flex. Constructed from premium stainless steel, this 6-inch blade is hollow-ground for consistent flexibility when bedding tape or smoothing joints. The integrated Hammer Head zinc-alloy end lets you reset protruding nails without setting the tool down, while the ergonomic overmold grip keeps things comfortable during high-repetition taping and patching.
