Nothing is perfect and no knife can get close to it. No matter how sharp and qualitative a metallic knife is, a simple view over a microscope will still show irregularities in the blade. With three nanometers in thickness or even less, the blade can be so sharp that it will slice molecules. It is way sharper than high-end steel surgical scalpels too. When done correctly, the edge will be very sharp. What makes obsidian knives so interesting?Ī well-crafted obsidian blade will bring in an impressive cutting edge. On the same note, it could break while in use and its sharp edges could cause severe injuries. It will lose its hardness, so it becomes more likely to break down. Simply put, drilling holes into obsidian and fitting a handle the right way may not be the smartest solution. If the handle is made of different materials, the two parts are usually connected through a primitive mechanism. Warriors also used deer antlers for handles. In ancient times, handles were made of other materials, such as wood. It could be a full one-piece unit based entirely on obsidian or it could be a mix of obsidian and another material for the handle. The handle can come in two different varieties. What is an obsidian knife?Īn obsidian knife is a knife made of obsidian. Back then, it was used as a weapon, mostly because of its hardness and sharp edges. It was found in Ethiopia, yet further archaeological studies have discovered that obsidian has been used thousands of years before its official discovery – back to the neolithic times. The volcanic glass was initially discovered by a Roman explorer named Obsidius, hence the name. Since it is natural, it is said to have a bunch of metaphysical properties as well, so it is often used in this industry for spiritual purposes. Obsidian is also used as a gem or a piece of jewelry. It is also amorphous and brittle – in other words, it breaks down with extremely sharp edges. The volcanic glass turns into a rock and becomes quite hard.
