What is an Obsidian Knife?

Obsidian blades are glass knives created using natural obsidian instead of man-made glass.

We will learn more about this unique blade in this blog post.

Obsidian Knife

Obsidian: The Volcanic Glass

Obsidian is a naturally occurring, volcanic glass. It forms when molten lava rapidly cools, without passing through the liquid state, and is therefore not known as a ‘crystal’. It is formed from a chemical process called vitrification.

It’s also known as the stone that shimmers because of its unique transparency and refraction capabilities.

Manufacturing

Flintknapping is the process of making tools out of stones. It is the same process used to make obsidian blades. The technique involves striking the raw material so it would break and form until the desired shape is achieved.

Benefits

Sharp

The cutting edge of these blades is quite impressive. In fact, when examined under the microscope, it’s found that the edge of these blades is perfectly smooth. Compared with the best steel blades out there which have irregular edges when examined under the lenses, obsidian knives are way sharper.

Cool

Obsidian knives do not conduct heat. In fact, they can be used on the hottest materials in the kitchen and don’t burn as steel blades would. These blades are also great to have when you’re making julienne cuts and want to leave your hands safe from burns.

Decorative

These knives are a great addition to the antique and modern kitchen decor. Glass knives are created with natural volcanic obsidian by artisan knife makers who carve and temper them to the desired shape.

Maintenance

The use of this blade requires proper care to maintain the edges. The following must be kept in mind to ensure that your blades are in tiptop condition all the time.

  • These blades cannot be sharpened on steel. Instead, a flat ceramic or glass surface will be needed to flatten the blade and edges.
  • The blade can be maintained by rubbing the edge with wet leather regularly. This makes sure that no moisture collects on the blade and erodes it in time. 
  • In order to avoid cracking or breaking, it’s recommended that diamonds be stored in the original packaging or a protective sheath.
  • Before cleaning your obsidian blade, make sure it is cool enough to avoid cracking the knife. You can either put the knife in a tub full of ice or place it in the freezer for several minutes.

Drawbacks

Brittle

Obsidian knives are less durable than steel knives. They are brittle. They also break more easily when used on hard substances like frozen foods and bones.

Limited use

Blades of this kind are picky when it comes to the tasks they can do. Definitely, they cannot handle tasks that require heavy-duty use.

Final Verdict

In a nutshell, obsidian knives continue to grace the world of knives with their beauty and sharpness. They may not be as popular as steel ones but they are still used by artisans and professionals in the industry all over the world. Their unique properties and design make them a great choice for every knife collector out there.

So if you are looking for a unique blade to add up to your existing collection, this might just be the one you are looking for.
