Six Great Dive Knives in 2022
ScubaLab tests a wide variety of asseccories, including dive bags, dive lights and dive knives. Each test is aimed at evaluating the key characteristics of each specific type of gear so divers can in turen evaluate what works for them.
How We Test a Dive Knife
Knives are evaluated by how effective they are at cutting a variety of lines that divers may encounter underwater. Ergonomic factors include comfort of the grip, security and accessibility of the sheath, and ease of maintenance. Resistance to corrosion is gauged by soaking the knives in salt water and documenting the results.

The grip of your knife should offer comfort and control, and mounting options should be secure but easy to access. Knives that come apart for cleaning are easier to protect from corrosion.
