Aqua Lung Zak 1 Dive Knife

The Aqua Lung Zak Knife offers straight-forward simplicity with uncompromised cutting ability. Available in two versions the Zak 1 offers supreme cutting ability.

The 4” stainless steel blade resists rust and is substantial enough to put some heft behind your cuts or sawing. The tough point of both versions of blade is tough and ideal for spearing fishing.

The ergonomic handle has been indented and rubberised to make it comfortable and grippy even when wearing big gloves so that it doesn’t slip when you’re using it.

The Zak knife comes with a robust sheath with adjustable straps so you can attach it to your arms or legs. Clips on the back of the sheath make it possible to attach to your BC.

Key Benefits

  • Stainless Steel Blade - Constructed from corrosion resistant stainless steel the Zak Knife is super-strong. With a reasonable degree of care the blade will remain rust free for years of dives to come.
  • Ergonomic Grip - The grip has been indented and shaped to be comfortable even wearing dives ensuring it doesn’t slip during use.
  • Visible Orange Grip - Bright orange highlights on the grip make it visible in in low light in case of an emergency.
  • Sheath Included - The Zak Knife is supplied with a tough sheath, protecting your knife from damage.
  • Adjustable Straps - Strap the sheath to your legs or arms for total convenience.
