Dive Knives With a Blunt End

August 22, 2022 4 min read

A diver's knife can be a handy tool for cutting thick ropes. Serrated edges are better for this purpose than big saw teeth, which can snag fibers of ropes. Make sure the serrated edge runs the length of the blade and near the tip, since the notch on a straight blade can snap a monofilament. If the blade does not have a serrated edge, make sure the notch is at the tip, where it can be more useful. Good sharpened knife is good to have while diving, but be careful and use it safely.

Blunt End

When you are diving, a knife with a blunt end is essential for keeping you safe. Many commercial divers choose these knives. They are made from high-quality steel that is not easily corroded. You can choose from black, blue, or yellow knives. A professional grade knife is also ideal for commercial divers. These knives are more durable and have a more pronounced blunt tip to limit the chances of an accidental cut.

Dive knives come with blunt or sharp tip options. The blunt end is safer for the user, and the blade can be used as a screwdriver, which is helpful when you're digging in the seafloor. It is also safer for the environment because the knife can't puncture the water. Sharp knives are preferred for spearfishing and fine cuts, but can cause accidental accidents. It is best to keep a knife with a blunt tip in a sheath at all times. Not all knives are sharp, but some models are.

Line-Cutting Notch

Dive knives are a great tool to use for cutting fishing line. Most knives feature a notch for cutting line, while others have other features, like a bottle opener or a hammer on the handle end. If you're not a fisherman, dive knives can even serve as a tank-knocker. Here are a few things to look for in a dive knife.

Dive knives come with a variety of blades with varying cutting edges. A plain edge is found closer to the tip of the blade, beneath the curve. A serrated edge is located closer to the handle and provides more leverage for tougher cuts. Many dive knives feature a combination of both blade types, and can be used for a variety of different cutting jobs. And a plain edge is easy to sharpen - anyone with a basic sharpening tool can keep their dive knife blades as sharp as possible.

Corrosion Resistance

When it comes to the blade material, steel is the most durable option. Titanium is corrosion-resistant, but is much more expensive than stainless steel. Stainless steel is softer and easier to sharpen, so it's a cheaper choice. Steel knives can be either serrated or non-serrated. Serrated blades are better for cutting seaweed, while non-serrated blades are better for cutting plastic.

Titanium is a great material for dive knives, but it's harder to sharpen. Titanium is more expensive than stainless steel, and it's not rustproof, so it's not a good choice for most knives. Most dive knives, however, are made of stainless steel, which is more durable, but isn't rustproof. Stainless steel has been used in knife blades for decades to avoid rust.

Stainless Steel

A diver's knife must be able to stand up to corrosion, which can occur in salt water. Stainless steel blades hold an edge very well in this environment, although 420 stainless is slightly better for corrosion resistance than H1 stainless. Titanium knives are also popular, as they are naturally corrosion resistant and require less sharpening than stainless. But there are some downsides to both types of steel.

Dive knives come with different types of grips. The grips you choose for your knife will depend on your reaction to the shape and texture. For example, if you are a large diver, you don't want a knife that is large enough to cut through a fishing line. Instead, go for one that is medium-sized. The blade and grip should be about the same length - a 4-5 inch blade and an equally sized grip.


Dive knives come in different sizes and shapes. Most models feature a blunt end that is sharp enough to cut rope and fishing line. You can also get dive knives that feature a bottle opener or hammer. These knives are also useful for cutting through tough rope or equipment. If you're planning to use one in the water, be sure to have both hands free. This way, you can use the knife without letting the blade slip out of your hands.

A good knife should have a reliable sheath, and the blade should be able to be folded for easy storage. Many knives also have a metal butt, which is a simple metal cap at the bottom of the handle. Besides cutting, it can also serve as a tap hammer. This is especially useful for divers who don't want to carry a heavy knife all the time.


There are several reasons why divers should choose a knife with a blunt tip. For instance, if you only plan to use the knife for cutting and prying, a blunt tip will be the most useful. However, if you are more into maintenance or spear fishing, you should go for a dive knife with a sharp tip. Here are a few tips to keep in mind when choosing a dive knife.

First, look for a knife that comes with a line cutter and a proper sheath. Without a knife sheath, you can risk losing it. Most dive knives are fixed-bladed and full tang. The handle is typically made of plastic and is easy to grip. Some knives even have a serrated edge on the back of the blade. This makes them ideal for cutting ropes and other materials, such as nylon rope.
