1. Gear Aid Akua Rescue and Dive Knife
The 3-inch titanium-coated stainless-steel blade of the Akua is equipped with a line cutter, straight and serrated edges, and a blunt screw/pry tip. The blade ends in a bottle opener/hammer. The sheath is designed to drain water and can mount anywhere thanks to its removable belt clip, webbing mount and lanyard holes. $29.95; gearaid.com
2. Cressi Titanium Grip
Bigger isn’t always better — if you get tangled in close quarters, a big thigh-mounted knife can be cumbersome. Smaller knives, like the sleek and stylish Titanium Grip, can be a lifesaver. This lightweight knife is easy to unsheathe and can be mounted in a variety of ways to keep it accessible. The rigid titanium blade features a sharp tip, straight and serrated edges, and a line cutter. $72.50; cressiusa.com
3. Spyderco Dragonfly 2 Hawkbill
This compact cutter might be small — it measures just more than 3 inches when folded — but don’t let its size fool you. The sturdy grip offered by the index-finger choil allows for ample cutting power and control. Combine that with the fully-serrated edge of a hawkbill blade made out of rust-resistant H1 steel and you’ll make short work of any line. $97.95; spyderco.com
