Master HVAC Cuts with Precision and Durability

Streamline your ductwork installations with the Klein Tools Double-Edged Duct Knife (DK16). Engineered specifically for HVAC professionals, this versatile tool features a premium 5.5-inch stainless steel blade with dual cutting edges. One side boasts an aggressive serrated edge ideal for sawing through tough duct board and flexible duct wire, while the other side offers a razor-sharp smooth edge for cleanly slicing through insulation and foil backing. This dual-design eliminates the need to switch tools mid-job, maximizing your efficiency on the job site.

Built to withstand the rigors of daily use, the DK16 is constructed with a reinforced steel tang that extends through the handle for superior strength and stability. The ergonomic, cushion-grip handle is designed for all-day comfort, providing a secure, non-slip hold even in humid or dusty environments. It also features a solid stainless steel striking pommel on the end for hammering or driving. When not in use, the knife locks securely into an impact-resistant hard sheath, complete with a belt clip to keep this essential tool at your side and ready for action.

Pro-Tip: When cutting flexible duct, use the serrated side of the blade to saw through the outer jacket and the wire helix coil. Then, flip the knife over and use the smooth edge to cleanly slice the inner insulation and liner. This technique prevents snagging and ensures a tight, professional seal.
