![]() A blinded histologic review suggested that obsidian wounds contained fewer inflammatory cells and less granulation tissue at 7 days. ![]() The blades, which have edges only a few molecules thick, are 100 to 500 times sharper than the traditional surgical steel scalpels (The University Record 1997). At 42 days, all wounds were barely detectable, thus precluding scar width analysis. The technology to make scalpel blades out of smoky obsidian, a volcanic glass that allows for the sharpest blade production, was first developed by the late Don Crabtree in the late 1970s. At 21 days, scar width was not different in the two groups. Scar width, however, was significantly less in the obsidian wounds at 7, 10, and 14 days (p < 0.005). An obsidian blade is 3 nanometers thick, capable of cutting BETWEEN your cells, allowing for a much more painless surgery. Tensile strength of the two wound types was not different at 7, 14, 21, and 42 days. Surgeons must be very careful to cut only soft tissues with the obsidian scalpel. Both obsidian and diamond blades have their uses. 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 scalpels, the cutting edge of the blade being only about 3 nanometers thick. It was pointed out that surgical steel isn’t actually that good. Jump to page: Results 1 to 10 of 20 6Likes. Obsidian scalpels are more expensiveabout 100 eachbut they can be used many times before they lose their keen edge. Scalpel vs straight razor of 2 1 2 Last. Many surgeons also report a sense of tactile feedback with a steel blade, which can be especially helpful for less experienced surgeons, or even surgical residents. Each rat received two parallel 8-cm dorsal skin incisions, one with an obsidian scalpel and the other with a surgical steel scalpel (no. Steel scalpels cost about 2 each, and surgeons use them just once and throw them away. Most scalpel blades, surgical scissors, and forceps are made from stainless steel since it tends to resist rust and is more cost-effective. In order to determine if skin incisions made with obsidian were superior to those made with standard surgical steel, wound tensile strength, scar width, and histology were assessed in 40 adult male Sprague-Dawley rats. There are several anecdotal clinical articles claiming wound healing and scar superiority using obsidian (volcanic glass) scalpels. A comparison of obsidian and surgical steel scalpel wound healing in rats.
