Overview

The Malco DK6S Double-Sided Duct Knife is designed for on-site duct work, offering both precision and versatility. With a 6-inch blade set in a 10-inch overall length, it provides dependable control when trimming flexible duct and duct board. One edge is serrated for tougher surfaces, while the opposite edge remains smooth for clean lines.

Design and blade

  • Stainless steel blade for durability and long-term sharpness
  • Double-edged configuration with one serrated edge and one plain edge
  • Resharpenable blade to extend tool life
  • Pierces outer skin, insulation, and liner of flexible round fiberglass wool duct
  • Cuts in either direction for controlled maneuvering in tight spaces
  • Ergonomic cushioned grip for a comfortable, secure hold
  • Puncture-resistant nylon sheath included for safe transport and storage

On-the-job versatility

This blade is well suited for retrofit and installation tasks where ducts run through confined corridors or around obstacles. The dual-edge design supports blind cuts in flex duct, while the 10-inch length helps keep your hand clear of the work surface. It handles both flexible fiberglass wool duct and duct board with steadiness.

What you can expect

  • Reliable performance on flexible duct projects thanks to a sturdy, resharpenable blade
  • Two cutting options (serrated and smooth) for different material textures
  • Secure on-site handling through an ergonomic grip and a protective sheath
  • Compact yet capable tool that complements standard duct work kits

Included

  • Puncture-resistant nylon sheath for safe transport
  • Malco DK6S duct knife with double-edged blade
