When modern drywall was introduced in 1936, it was Hyde the industry called on to design what became the drywall joint knife that we all still use today. For decades before and after that call, it was Hyde that supplied the tools of choice for professional painters, drywall pros, wallpaper hangers and other tradesmen. This 0.63 inch H x 6 inch W x 8 inch L knife is made from high quality carbon steel, ensuring durability and strength for even the toughest jobs. Its pointed tip allows for precise and accurate application of drywall joint compound, while the comfortable grip handle provides maximum control and comfort.
