![]() However, I fear that these methods could possibly weaken the (already delicate) structure of the obsidian. Plastic dowels are made of polyoxymethylene. The relatively inexpensive obsidian scalpel is a good substitute for an expensive diamond knife. ![]() I have considered subjecting the scalpel to strong dose of UV radiation or perhaps 'cleaning' the scalpel with Povidone-Iodine (Betadine). It is ideal for applications where an extremely fine cutting action is required or where trace metals from ordinary scalpel blades cannot be tolerated. 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. Obsidian has been used as a cutting tool since the Stone Age, but modern versions of obsidian scalpels are manufactured by a Virginia archaeologist using a pressure flaking process. 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. Obsidian is used by some surgeons for scalpel blades, as well-crafted obsidian blades have a cutting edge many times sharper than high-quality steel surgical. The black volcanic glass is up to 100 times sharper and much smoother than stainless steel scalpels. 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. Used by some surgeons by some surgeons, the scalpel blade has a cutting edge several times sharper than that of high-quality steel surgical scalpel blades in the market. Now these scalpels are pretty fragile, with some of them having a thickness of the order of 0.1 mm. There are several anecdotal clinical articles claiming wound healing and scar superiority using obsidian (volcanic glass) scalpels. ![]() 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 This is because the scalpels have blades that can hold the edge a long time as compared to utility knives. There are two types of vasectomy: traditional and no-scalpel vasectomy.
