Dive Knife Buyer’s Guide

A dive knife is a safety device! It's primary purpose is to cut fishing line and other entanglements. Aqua Safaris believes that a knife or other cutting tool is basic safety equipment all divers should have with them at all times. If you are diving at a wharf or pier or similar location where line-fishing is common, you should consider having a back-up cutting tool as well. Your knife need not be large, but it should be sharp, securely sheathed and easily accessible with one hand.

The number one problem with dive knives is loss due to poorly designed sheaths. Few dive knives come with good sheaths! A good sheath needs:

1. One-handed access by either hand when needed in an emergency,
2. Rustproof or nonmetallic spring retainment system,
3. Method of securing within the “golden triangle” between the shoulders and navel.

Aqua Safaris does not recommend leg or arm sheaths. A knife mounted on your arm is not accessible with both hands, and a leg-mounted knife may not be reachable if a diver becomes entangles. Furthermore, a leg knife itself becomes an entanglement hazard. A BC mount is ideal; hose-mounted sheaths are also OK. In addition to being safer, a knife already mounted to your BC goes on when you put on your BC—one less item of gear to put on, minimizing your time to get dressed.

For the purpose of cutting line, any number of knife designs, scissors and specialized line cutters will work, as long as they are securely mounted where you can get to them quickly with minimum thought. The mounting method is more important than the tool itself! Whatever you use, be sure that all steel parts (blades, screws, handles) are made of high-nickel low-carbon stainless steel. High-carbon “stainless” steels may hold a sharper edge, but they still corrode in salt water. You might choose your knife for auxiliary functions. You may find that the most common actual use for your dive knife is to fix lunch! One reason for a longer knife is for a prying tool, for example, if you are collecting shellfish. A blunt-tipped knife is perhaps a little safer for the diver and can double as a screwdriver or pry tool, but many divers prefer a sharp-pointed knife for poking into things; just don't poke yourself! Blades of two or three inch length are plenty big enough for most applications.

Some divers prefer scissors. The kind used by emergency medical personnel to cut away clothing makes a great alternative to a dive knife. These scissors can give excellent leverage for cutting line and even thin cable. (You can cut a penny in half!) Make sure you get scissors with all stainless parts and make sure you have a good sheath. You can also get specialized “line cutters” which have the sharp edge protected inside a plastic hook (great if you are uncomfortable with an exposed blade). Check out our knifes on this web page.
