Buying Guide
What matters when choosing a titanium beta alloy dive knife:
- Material and corrosion resistance: Titanium alloys offer superior saltwater resistance but can affect edge retention and sharpening needs. Consider beta titanium for a balance of strength and weight.
- Blade geometry and edge options: Serrated vs. straight edges, and blades with line-cutting notches provide different capabilities for rope, kelp, and line work.
- Handle design and grip security: Textured grips, glove-friendly ergonomics, and secure blade locks improve control in wet conditions.
- Deployment and attachment options: Folding designs with pocket clips, BC attachment points, and leg straps enhance accessibility and gear integration.
- Size and portability: Shorter blades are easier to carry and deploy for recreational divers, while longer blades offer more cutting leverage for heavy tasks.
