    Scuba Saves
    The best dive knife is one that will work in that instant you need it. Like many other knives, it isn’t a weapon. It’s just a tool to be used that will help to keep you save when there’s a dangerous situation in the water.

It’s usually the only tool you have with you, so it needs to be as versatile as possible.

    What Are the Basics of a Dive Knife?

    You’ve got two basic options with the modern dive knife: folded or fixed. Folding blades are smaller and more compact and fit into pockets. Because they fold up, the risks are reduced that an accidental puncture is going to happen. If you’re wearing gloves, however, a folding knife can be a little cumbersome.

    Fixed blades are the usual diving knives that you’ll find today. The best thing to consider with this type of blade is the sheath that helps to protect it. If the fit isn’t smooth and easy, then there’s a good chance that you’ll drop the knife during a dive. A tight fit can also lead to an accidental slicing or puncture that you don’t want.

    What Are the Advantages of the Best Diving Knife?

    The best dive knife is typically made from titanium. This is because they are incredibly strong and are resistant to corrosion. Titanium knives can sometimes be problematic, however, because they can be difficult to sharpen. Because they are maintenance-free, however, they could be a viable solution for your diving needs.

    Steel knives are a good second option. They hold an edge well, are easy to sharpen, but require more overall maintenance to keep them from rusting. Steel knives come in two different types of alloys. The 300 alloys are more like titanium knives – easier to care for, but more difficult to sharpen. 400 alloys stay sharper and need to be protected from rust. Serrated or straight edge blades are typically user preference, but do get a line-cutting notch and look for metal handles first to get the best possible experience.

    Most dive knives are going to be found on a site like Amazon for around $50 and be a great knife. Some are cheaper and require more maintenance, while others are more expensive and require more effort to sharpen.
