Buying Guide

Blade material and corrosion resistance

Choose stainless or titanium-tempered blades—titanium offers superior saltwater corrosion resistance while stainless provides durable, budget-friendly cutting performance

Tip style: blunt vs dual/sharp

Blunt tips reduce puncture risk around divers and suits, while dual-tip or sharp points are better for precise tasks like cutting bait or freeing catches

Handle grip and glove compatibility

Look for glove-friendly, textured handles that stay secure when wet; comfortable ergonomics matter for one-handed use during dives or spearfishing

Sheath and mounting options

Sheaths with secure retention, multiple mounting positions, or quick-release straps keep the tool accessible and prevent accidental loss underwater

Integrated tools and safety features

Line cutters, serrated edges, and blunt-edge rescue designs add versatility and safety for cutting fishing line, nets, or performing rescues
