What Is An Obsidian Knife?

Obsidian blades are made of obsidian. It usually comes with two handle options. By combining obsidian with other elements, one might be able to make an obsidian handle. Wood or other materials were usually used for handles before obsidian became popular. Various cultures used deer antler handles.

An easy mechanism is used to link two or more materials when the handle is made of more than one material. A hole drilled in obsidian and a handle attached properly may not always be the best approach.

In turn, this causes its hardness to decrease, which causes it to become brittle. However, its sharp edges can cause serious injuries, and it can break when in use.

These knives are so sharp that they have been used by surgeons as scalpels, with a blade of three nanometers, when operating on various animals (not on humans because it is not yet approved by FDA). This type of blade and knife is very beneficial for many types of activities, here is a couple.

Uses of Obsidian Knife

Preparing Meals

Whether you are cooking a meal for the whole family at home or out in the wilderness while riding solo, an obsidian knife is definitely the knife for the job. Although the blade is jagged, it makes clean cuts in both hard and soft foods without requiring much force on your side. This youtube video is an interesting source that shows just how well an obsidian knife can cut a tomato without bruising or squishing it. Also, if you are out camping in the woods and need a sharp blade to skin a small animal for a meal over the campfire, an obsidian knife does a great job, especially since it does not dull at a fast rate when in use. The obsidian knife could also be used in starting fires because of its flint like property when fractured. This knife is a perfect companion survival knife for everyday activities while camping, but it is also a cool kitchen knife to pull out when wanting to impress company or when looking to spice up your cooking life.

A Flint Replacement

Like I mentioned quickly above, an obsidian or an obsidian knife can be used in place of flint when used with steel. A video by Larry Rogers shows how to make a fire start by using the two materials. He mentions that there is a special balance of sharpness and fragileness that one must keep in mind while striking the obsidian with the steel in order to successfully produce a spark and ultimately a fire. A larger piece of obsidian is preferred, like the one used in the video, but a blade of an obsidian knife will also do the job. The ability for obsidian to act as a flint is especially nice when you do not have anything with you that will aid in making a fire.

Cutting Large Pieces of Wood

The blade of the obsidian knife is incomparable to others because of its ability to stay sharp and sturdy. It also makes nice clean cuts which are important in being efficient when cutting wood. This factor of the obsidian knife makes it a must-have for all outdoorsmen and campers.

How to Sharpen Obsidian Knife Blades?

Obsidian Blades are made from a variety of materials such as metal, titanium, plastic, ceramic, glass and obsidian. Obsidian is generated in nature when felsic lava is forced from a volcano and does not experience the process of crystal growth while cooling. Because of its chemical form, which allows it to get nearly molecular thinness, it is an ideal element for making surgical scalpel blades. It is a naturally designed glass that can be crafted to a considerably sharper cutting edge than steel blades. The substance is even used in some sports knives. If your obsidian knife blade has been worn down and could use sharpening follow these easy steps:

  • Stand in front of the kitchen counter and place the sharpening stone vertically on the countertop.
  • Place the obsidian blade flat on the stone, placing the length of the knife at a 45-degree angle to the stone.
  • Take the handle of the knife, with your index finger along the blade’s backside.
  • Lift the blade’s flat side surface off of the stone at a 20-degree angle, but keep the cutting edge over the stone.
  • Move the blade toward you, while keeping the edge connected with the stone. While doing so, maintain the 20-degree angle reached when raising the backside of the blade from the stone and the 45-degree angle length position of the knife to the stone. Put a little pressure as you move the blade opposite the stone.
  • Switch over on the other side and redo the process on the other side of the Obsidian blade while keeping the position of the angles.
