How To Choose The Best Dive Knife – Buying Guide

What-to-look-for-in-a-dive-knife

As a knife is a crucial safety device to have underwater, it is important to get the best. Best dive knife reviews agree that looking for the following characteristics are of the utmost importance when picking one that is right for you.

Size

Bigger isn’t always better when it comes to the best dive knives. Even though they can range from 3 to 6 inches we find that the 3.5 to 5 inch is the perfect sized blade. This gives you enough travel to easily cut rope or other material and still be compact enough to carry around without too much added bulk.

Edge

There are two main types of blade edges. A good knife should have both. One side, or part, of the knife should be straight while the other is serrated. If you have to choose between these features look first for a serrated blade. It will be able to cut through tougher material and stays sharp longer.

Material

Normal knifes do not need to stand up to the harsh environment of the ocean. Different material will react with the salt and could cause rusting. We suggest looking for a knife that uses a stainless steel or titanium construction.

The stainless steel option will require regular maintenance and sharpening. A lower number, around 300, will indicate a higher quality knife, but will be harder to keep sharp due to high carbon count. You will have to rinse these dive knives after each use and even apply oil or wax to keep it from corroding.

A titanium blade is a much higher quality and cost knife that requires minimal maintenance. The only drawback to these knives is that they are hard to sharpen but the best dive knives shouldn’t require sharpening that often. This option will not rust or deteriorate over time and will be what you need at all times.

Tip

Dive knives can have a pointed or dull tip. Some will appreciate a blunt knife so they don’t puncture things they don’t intend to while others may need that option. New divers may opt for the blunt option as it can be safer underwater.

Attachments

Most knives will come with a way to attach so you will not lose it. This could be as simple as a loop to allow you to strap it to your suit. Others come with a strap which allows you to attach it to your leg or thigh. This will give you quick access to the knife while having it out of the way. The only drawback is that it could get caught on things.

Globo Surf Overview

When scuba diving it is highly recommended that you take every precaution possible. While it is a very beloved sport, it is important to dive prepared and that includes having the best dive knives. As typical dives are in salt water, having a corrosive resistant knife is important to ensure the full functionality. When you are underwater you are in a much more limited position than in the dry world, it is important that the one knife you have with you can do the job properly. Having the best diving knife will ensure that you are able to cut your way free of fishing wire or rope when underwater should that situation arrive. As a bonus, these knives are sharp enough to be doubled as a fisherman’s knife.
