The AquaLung Argonaut Dive Knife combines simplicity with rugged materials for one of the best and toughest dive knives on the market. A single piece of titanium is forged into a corrosion resitant, lightweight superstrong dive knife.


Full Tang Titanium Blade is made from a single piece of 4mm titanium so there are no joins or weak points to come loose or break. The whole knife is then coated in Electrophoretically Deposited Paint, EDP, for a tough black finish which is then laser etched before the blade is sharpened. The butt of the knife is pointed for use as a glass breaker in an emergency and the handle has skeletoned holes that can be used as hex wrenches.


5mm Paracord Handle wrapped twice for a nice grip that can be used for a whole range of situations in an emergency and is tied off with a 5" leash. Wrapped a 1/2" from the hilt to provide a spot for the forefinger and extra grip for the sheath.


2mm Kydex Plastic Sheath is thermoformed around the blade to make a secure sheath for your Argonaut with multiple 3mm attachment points and slots for threading straps before the logo is laser etched onto the exterior.


Spartan and Blunt Tips for your choice of cutting tool; the Spartan Tip with a spear head pointwith one side featuring rounded die cut serrations to prevent snags on rope and the Blunt Tip with a blunted chisel tip for prying and turning screws with a full serrated edge of die cut rounded serration.

Line Cutting Notch
Some knife blades include a specially designed notch for cutting most forms of line or thin rope. Line is much easier to cut in a controlled manner when using the notch instead of slicing the line or rope using the sharpened edge of the blade. Close.
Overall Length
The overal length of the knife, cutter or shears. This length is measured with the sheath in place. Close.
Serrated Edge
A serrated edge makes it easier to cut through some materials, acting more like a saw than a straight blade. Close.
Sheath Material
Sheaths are typcially made from either plastic or webbing. Plastic housings offer impact protection and will incorporate a locking mechanism to help prevent accidental lose of the knife. Webbing sheaths are normally supplied with smaller, low profile back-up knifes and cutter and usually use a velcro tab to retain the knife or cutter. Close.
Tip Type
Standard knife blades are usually available with either a point or blunt tip. A pointed tip holds more a risk of accidental punction of other equipment or injury. A blunt tip reduces the risk of accident damage and is also handy as a lever if you need to pry something open. Close.

Sturdy knife

This is a sturdy, well made knife. The single piece of metal (handle and blade) is reassuring and no risk of breaking or bending. It is on the larger side so check the measurements against your needs. It has a slick design and looks good too.
