![]() However, I fear that these methods could possibly weaken the (already delicate) structure of the obsidian. He has made a good amount of money from the show. I have considered subjecting the scalpel to strong dose of UV radiation or perhaps 'cleaning' the scalpel with Povidone-Iodine (Betadine). He has starred in Duck Dynasty since its first show and now the show has already aired 11 seasons.I did try looking up the structure that obsidian assumes at the molecular level, with the hope that the knowledge would help me narrow down possible sterilization methods I could use here, but I drew a blank there as well. Knowing how delicate this thing is, I doubt conventional methods (such as autoclaving it) used to sterilize surgical tools could be safely applied in this case.Īs the use of obsidian blades in surgery is relatively new, I'm not surprised that I can't find any literature dealing with the sterilization of obsidian blades online. I don't actually plan on operating on someone with this, but all the same, I'd like to identify potential methods to sterilize such a blade. Now these scalpels are pretty fragile, with some of them having a thickness of the order of 0.1 mm. Glass will loose its edge on about anything.I recently came across this article on the use of obsidian scalpels in surgery: How Stone Age blades are still cutting it in modern surgery There's also nothing it cant cut, while glass which can be sharper, is only a 5.5 on this scale to 10 (diamond). To cut glass, jewels or just anything you want a precise cut on, you use diamond because it will keep its edge the longest, seeing as its the hardest. Like other volcanic glasses, obsidian is a lava that has cooled too. The color is commonly black, but may be some shade of red or brown, and cut sections sometimes appear to be green. Now days, we harvest non jewler grade diamonds and artificial diamonds to COAT blades with. obsidian (bsdn), a volcanic glass, homogeneous in texture and having a low water content, with a vitreous luster and a conchoidal fracture. is guided by constant reference to the record, and ends when the record has. If mine is harder, your just going to blunt your edge. Weaponry and martially themed obsidian production near the Moon Pyramid. If your mineral is harder on Mohs scale than mine, you can cut mine. look up Mohs hardness scale) that gives them their notoriety. As far as the famed diamond blades are concerned, its their HARDNESS (mineralogical term. ![]() Now days they are used in ocular surgeries when lasers are not available. We have had the sharpest knives on earth since before we could write. Obsidian, specifically, has been used for a very long time in the medical profession and was the prized tip for spears. Im not liable when you get cut or worse, you were warned. Some man made glass is specifically designed NOT to have these edges, so get a non shatter proof glass. Break a peace of glass and see how easy it is for that glass to cut you. These blades are actually MORE durable AND SHARPER than a diamond blade. The concoidal cleavage means a smooth cutting surface, and the amorphous, but bonded structure, means that you can get down to a molecule thick. If you take some obsidian and knap off two sides, you can get the two sides to be around 33 degrees or even less depending on how fast the glass cooled and what minerals it is made up of. This actually works to a glass knifes advantage. It does however have conchoidal cleavage, though its comparatively weak. Glasses being amorphous, do not have any cleavage so easy to shatter along. The repulsion of each carbon atom to each next will keep you from getting a stable edge. The two sides of the blade will always want to be 90 degrees from each other, but you may be able to grind it down to around 45. If the atoms are jolted just slightly out of place, the atomic repulsion will do the rest and your diamond will cleave.)Ģ. It's easier to break in two than a piece of glass the same size. This means that the edge will be flat because a large number of layers will just slog off of the cutting edge.(if you have a big diamond in your/your spouse's ring, you will want to be careful not to knock it on anything hard. ![]() Check out the geology related cleavage article if you want to know more) in all 3 dimensions. They have distinct 90 degree cleavage (look it up if you think breasts. When talking about the sharpness measured in atomic widths, you have to look at the molecular structure.ĭiamonds are cubic.
