Buying Guide

Blade material matters

Choose tempered or stainless steel blades for a balance of edge retention and corrosion resistance in saltwater conditions

Edge type and cutting tasks

Pick dual-edge or partially serrated blades for both clean cuts and sawing through braided line or kelp

Sheath and retention

Look for a secure sheath with multiple mounting options and positive retention to prevent loss during dives

Line-cutting features

Integrated line cutters or notch designs speed emergency snips without deploying the full blade

Corrosion protection

Opt for coatings, tempered finishes, or marine-grade stainless components to extend service life in saltwater
