![]() ![]() The glass has more practical uses also, for example the support pedestals for audio turntables have been created with obsidian since the 1970s. These small round nuggets of obsidian may have a grayish-white perlite matrix. Since obsidian will fracture down to a single atom, it is claimed to have a cutting edge five hundred times sharper than the sharpest steel blade, and under a high magnification microscope an obsidian blade still appears smooth, whereas a steel. If you have been to a crystal store or a natural science museum with a gift shop, you might have seen stones that you can buy called “ Apache tears”. The Mayan Indians are credited with using highly sophisticated obsidian blades first 2,500 years ago. ![]() 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 FST, we precisely craft over 1,000 products, and serve thousands of customers in universities, research facilities, biotech. 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. Obsidian is also a reasonably popular gemstone featured in different jewelry pieces. For over 48 years, the Fine Science Tools (FST) Group has been the leading distributor of precision European surgical and microsurgical instruments and laboratory accessories. It creates cleaner cuts and causes less damage to the surrounding tissue than almost any other blade we are able to fabricate. This delicate and incredibly sharp nature of obsidian is therefore sometimes used for scalpel blades by surgeons. A standard household razor blade has a fineness measurement of between 300 to 600 angstroms, and an obsidian blade, in contrast, has a measurement of just 30 angstroms. Today, some knives are still made with obsidian blades because the cutting edge can be almost five times sharper than highly refined steel. ![]()
