Sharpness depends on factors such as the edge angle, edge width, and the fineness of the cutting edge, and is aided by material hardness. This quality is found in a variety of naturally occurring forms, including certain kinds of rock , in plant thorns and spines, and in animal teeth, claws, horns, and other structures serving various purposes.
This edge is then refined by honing until the blade is capable of cutting. The extent to which this honing takes place depends upon the intended use of the tool or implement. For some applications an edge with a certain amount of jaggedness is acceptable, or even desirable, as this creates a serrated cutting edge. In other applications the edge ...
A sharp blade will have a distinct edge, like a corner, and may sing slightly from vibration, while a dull blade will have a round edge and the thumb will slip over it. A blade's sharpness may be tested by checking if it "bites"—begins to cut by being drawn across an object without pressure .
In machining, the rake angle is a parameter used in various cutting processes, describing the angle of the cutting face relative to the workpiece. There are three types of rake angles: positive, zero or neutral, and negative. Positive rake: A tool has a positive rake when the face of the cutting tool slopes away from the cutting edge at inner side.

sharpness — smallest carbide and grain for smallest apex reduce force in cutting; edge life — an index for the length of time an edge will cut based on lack of edge rolling or chipping; edge quality — toothy with large carbides or refined with small carbides; ease of sharpening — steel easily abrades on stone and forms a sharp edge
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.
