Buying Guide

Blade material and corrosion resistance

Look for stainless or titanium-tempered steel to resist seawater corrosion and maintain an edge with minimal maintenance

Blade tip: pointed vs blunt

Pointed or dual-tip blades work for puncturing and slicing; blunt tips reduce puncture risk when primarily cutting lines or nets

Sheath security and mounting

Check for a reliable sheath with straps or clip options that mount to the calf or BCD to prevent loss during a dive

Integrated line-cutters and serrations

Line-cutters or serrated sections improve performance on braided fishing lines and webbing compared with plain-edge blades

Handle grip and ergonomics

A textured, non-slip handle helps maintain control when wet or while wearing gloves; consider size relative to gloved hands
