The technology to make scalpel blades out of smoky obsidian, a volcanic glass that allows for the sharpest blade production, was first developed by Don Crabtree in the late 1970s. The blades, which have edges only a few molecules thick, are 100 to 500 times sharper than the traditional surgical steel scalpels. [7]
Obsidian scalpels may be purchased for surgical use on research animals. [63] The major disadvantage of obsidian blades is their brittleness compared to those made of metal, [64] thus limiting the surgical applications for obsidian blades to a variety of specialized uses where this is not a concern.

A scalpel, lancet, or bistoury is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, podiatry and various handicrafts. A lancet is a double-edged scalpel. Scalpel blades are usually made of hardened and tempered steel, stainless steel, or high carbon steel; in addition, titanium, ceramic, diamond and even ...
Knife making is the process of manufacturing a knife by any one or a combination of processes: stock removal, forging to shape, welded lamination or investment cast. [1] Typical metals used come from the carbon steel, tool, or stainless steel families. Primitive knives have been made from bronze, copper, brass, iron, obsidian, and flint.
Glass knife. A glass knife is a knife with a blade made of glass, with a fracture line forming an extremely sharp cutting edge. Glass knives were used in antiquity due to their natural sharpness and the ease with which they could be manufactured. In modern electron microscopy glass knives are used to make the ultrathin sections needed for imaging.
The most common blade materials are carbon steel, stainless steel, tool steel, and alloy steel. Less common materials in blades include cobalt and titanium alloys, ceramic, obsidian, and plastic. The hardness of steel is usually stated as a number on the Rockwell C scale (HRC). The Rockwell scale is a hardness scale based on the resistance to ...
