This is the same reason why most collectors and knife lovers have them.Įven though you won’t be able to use them the same way as a normal knife due to their brittleness, they will still perform well when you use them.įor comparison, an obsidian glass knife will be sharper than the best high carbon steel knife that you can find out there. Well, these knives have found their way into surgery because of how sharp and precise they can get. What are the pros of an obsidian knife?įor something so brittle, why are we even talking about it? Now, consider the fact that obsidian is even more brittle than that ceramic. Imagine if that bulk of ceramic that was your kitchen sink is fined down into a thin sheet of the knife blade – and imagine how easy it would be to break. However, it takes enough force and impact to see it start breaking and chipping. That is made of ceramic and you can see how hard it gets. If you have never come across an obsidian material before, think about your traditional bathroom sink. However, even though it cools into a hard material, it is still brittle and can be shattered on impact. That cooling hardens the material which makes it possible to obtain as a mineral (even though obsidian is not considered a mineral, no thanks to the lack of crystalline structure). That said, the obsidian is formed when molten lava runs and cools rapidly. This includes regions in Argentina, Chile, Georgia, Canada, Australia, and Japan, among others.
Since it is a volcanic material, it can only be found at volcanic sites. What are the pros of an obsidian knife?Ī little history as to where the material for this knife is found won’t hurt.
