Some divers prefer a dedicated line cutter instead of a dive knife. The DGX premium quality { 5 in | 13 cm } Tek Line Cutter is made from titanium alloy, offering exceptional corrosion resistance. This design is gripped between the index finger and middle/ring fingers, and held in place using the thumb. The price also includes a hogarthian style sheath which fits on a webbing harness waistband and has been enhanced with a Velcro® flap and pull tab that holds the knife securely while still allowing reliable one-handed usage.
