Our ScubaLab team takes a first look at some of the newest gear to come into the dive market. See how the latest dive knives compare in features and price.

With its 5-inch blade and leg-strap sheath, the Talon has a classic look familiar to anyone who ever watched Sea Hunt. But the details are all Space Age, with a titanium drop-point blade with a serrated back edge and line cutter. It releases from the sheath with a squeeze of the locks, and the ergonomic handle is pierced for a lanyard and has a hammer tip for tank knocking.

Light (1 ounce on our postal scale) and compact, the SK75 has a 3-inch titanium blade with a serrated back and a line cutter. The locking plastic sheath has strap slots as well an adjustable double-thumbscrew connector to attach to any BC grommets from 3.7 to 5.3 inches apart, or you can use the included rubber straps to hang it from the inflator hose.

Small but tough, the X-Cut is shaped from hardened titanium, with a flat profile and a soft sheath that will attach to BC straps or tuck into a pocket. The 2.5-inch round-tip blade has both smooth and serrated sections, and a line cutter. The skeleton handle has finger notches and a grooved thumb stop for a secure grip, and it is drilled for a lanyard.

A tidy 4 inches long when folded, the Saver Salt flips open with one hand to reveal a 3-inch, sheep-foot blade made of aggressively serrated H1 steel, which is impervious to rust and hardens with use. The molded handle is waffle textured for a secure grip, has a reversible titanium pocket clip, and is available in black or bright yellow.

Divers used to have two choices: knives that would rust, or knives that wouldn't cut. New materials and innovative designs have changed that - here are four new knives that might help you get to the point in your search for something sharp.
