Sharper than a dive knife, the Z-Knife is preferred for cutting through monofilament and braid line.
In the early 1980's cave divers were in need of small, line-cutting devices. Since the application was strictly for cutting lines, they looked to other sports and adopted the parachute line cutter known as a Z-Knife.

The Z-knife was a protected blade stored away in a pouch. Today, the pouches have evolved, but the knife is still the same one parachutists' use to cut away a chute. Sharper than a dive knife, the Z-Knife is preferred for cutting through monofilament and braid line.
