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.

Key Features

  • Dual-Edge Versatility: Features both a serrated edge for sawing and a smooth edge for slicing flexible duct and insulation.
  • Durable Construction: Stainless steel blade resists rust and corrosion for long-lasting performance.
  • Reinforced Strength: Full steel tang design adds stability and prevents breakage under heavy pressure.
  • Impact Resistant Sheath: Includes a hard locking sheath with a belt clip for safe storage and easy access.
  • Striking Pommel: Solid stainless steel end cap allows for hammering and driving tasks.
  • Ergonomic Grip: Dual-material handle provides a comfortable, non-slip grip to reduce hand fatigue.
  • Optimized Size: 5.5-inch blade length offers the perfect balance of reach and control for ductwork.

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.

Good quality, but could have used better instructions
The kit was complete, and all the components were well made. However, if you aren't somewhat mechanical, it would be fairly easy to install the gaskets and backing plate in the wrong sequence. With better instructions, this would be a 5 star plus kit.

Don't pay boat shops for over priced services!
Boat shop wanted $400 dollars for a new water pump replacement. Got this on Amazon and watched a few utube videos. Took less then 2hrs to take apart and replace. I put it in a Alpha 1 gen 2 lower. Very simple process.
