Choosing the best dive knives depends on the type of diving you do and how much you are willing to pay. Dive knives range in price from about $20-$150, based on design, quality and material.
Like most dive gear these days, there is a variety of dive knives on the market, from folding knives to knives with built-in scissors. A lot of it comes down to personal choice. The bottom line is to make sure you buy a knife that is non-corrosive. Titanium is the choice material, though stainless steel also works.
- Serrated or straight edge: Serrated-edge knives are more common for diving. They are used to cut and saw rope, net, lines and kelp. Straight-edge knives cut fishing line and do other small tasks. Look for knives that offer dual blades -- straight and serrated.
- Size and design: A medium-length knife is compact but has a blade length that can get most jobs done. Look for a knife handle that is 4 or 5 inches long, with a 4-inch blade. Blunt-tipped knives help you avoid any accidental punctures of gear while diving.
- Sheathing: Leg-mounted sheaths look sharp, but holders that fit on your BC are much more convenient.
