A trusty dive knife is an essential part of any scuba diver’s gear. A good dive knife serves multiple purposes, from helping you navigate tangled fishing lines to prying loose a stubborn shellfish. But with so many options available, how do you choose the right dive knife for your needs?
Here are some key factors to consider:
Blade Material: Stainless steel is the most common choice, offering a good balance of durability and corrosion resistance. Titanium is lighter and even more resistant to corrosion, but it’s also more expensive and can be difficult to sharpen.
Blade Style: Serrated blades excel at cutting rope and line, while plain blades are better for slicing and precision tasks. Some knives offer a combination of both edge types for ultimate versatility.
Tip Point: A blunt or rounded tip minimises the risk of accidental punctures, while a pointed tip offers better piercing capability.
Size and Weight: Choose a knife that’s comfortable to carry and easy to access. A smaller, lightweight knife is ideal for recreational diving, while technical divers might opt for a larger, more robust option.
Locking Mechanism: A secure locking mechanism ensures your knife stays put when you need it most. Spring-assisted locks are easy to operate with gloved hands, while sheath friction locks offer a more streamlined design.
Beyond the Basics:
Some dive knives come with additional features that can enhance their functionality. Line cutters are built-in notches that make quick work of entangled lines. Sheaths with integrated pockets can hold spare parts or tools. Remember, a good quality sheath is just as important as the knife itself. It should secure the knife safely and be easy to access underwater.
Knife attachments: Consider how you want to attach your knife to you or your kit for easy access. You may want to strap your knife to your leg or arm, but if you want to remain more streamlined may choose to attach to your BCD.
Safety First:
Always treat your dive knife with respect. Remember, it’s a tool, not a weapon. Never play with it underwater and ensure you’re properly trained in its safe use.
By considering these factors and your individual diving needs, you can choose a dive knife that becomes a reliable companion on all your underwater adventures. Happy diving.
