Buying Guide

Blade material and corrosion resistance

Choose 300-series or 304 stainless or similarly saltwater-rated steel to resist rust and maintain edge after repeated exposure to saltwater

Cutting edge type

Opt for a combination of plain and serrated edges or an integrated line-cutter to handle both rope and fibrous kelp quickly

Sheath retention and mounting

Look for secure sheaths with multiple mounting options and positive retention to keep the knife accessible but locked in during paddling

Handle grip and ergonomics

Prioritize textured, non-slip handles and finger guards so you can operate the tool wet or with gloves on

Size and legal considerations

Select blade length and type that comply with local boating and diving regulations while still providing adequate cutting capability
