GET STARTED DIVINGLIVEABOARD DIVINGDIVE TRAVEL DEALSDIVE DESTINATIONSGEAR UP FOR SCUBA UPDATE PROFILESKIP FOR NOW HOW TO CHOOSE THE BEST DIVE KNIVES MATERIAL There are 2 different materials used to make a diving knives: titanium and steel. The TITANIUM DIVE KNIVES are incredibly strong and very resistant to corrosion. They’re also maintenance free. However, they can be hard to sharpen. The STEEL DIVE KNIVES are easy to sharpen, but they require more maintenance to prevent them from rusting. These knives usually come in two different alloys, 300 and 400. The 300 alloy is closer to a titanium knife, being harder to sharpen but requiring less maintenance. The 400 alloy on the other hand holds its edge well, but is more prone to rusting. SIZE A bigger knife doesn’t necessarily means it’s a one. The size of your diving knife should be determined by how you plan to use it. For recreational divers, a small dive knife with a 4 inch blade should be fine, as you’ll be using it just in case you get tangled but most of the time it will remain in its case. If you plan to use your dive knife for spearfishing, kelp diving or cutting fouled lines underwater, you’ll need a different size depending on your specific situation. TYPE OF BLADE The best dive knives can have a fixed blade or a folding blade. The KNIVES WITH A FIXED BLADE come with a sheath to store it safely. The advantage of this type of blade is you to take it out with one hand. The KNIVES WITH A FOLDABLE BLADE are smaller and lighter, and most of them lock in the open position to prevent chopping your fingers off when using it. These models can be hard to open with one hand. SHAPE OF BLADE There are two main parts to look at when choosing the blade’s shape of your dive knife: the edge and the tip. The EDGE OF THE BLADE can be straight or serrated. The straight blade is better to cut plastics or a nylon rope while a serrated blade will perform better to cut kelp and natural fibers. Don’t get caught up on this, just get a knife with a straight and a serrated part together. The TIP OF THE BLADE can be blunt, sharp or tanto (half way between the other two). A blunt tip is great to prying, digging, hacking, and chiseling. A sharp tip is great to cut and puncture, which makes them the popular choice for spearfishing. However, these tips are more likely to cause accidents and are not recommended for recreational divers. ATTACHMENT Where to attach your dive knife has been a hot topic among divers in the recent years. Traditionally, the most used place has been to carry the DIVE KNIFE ON THE LOWER LEG (opposite to the dominant hand). The disadvantage of placing it on the leg is it can easily get entangled with things underwater while diving. These days, more and more divers carry their DIVING KNIVES ON THEIR BCDS. This way you never forget it on the boat and it’s easier to reach in case you need it. SCUBA DIVING RESOURCESTABLE OF CONTENTSSCUBA DIVINGTABLE OF CONTENTS 1. BASICS 5. SCUBA EQUIPMENT 2.
