Scissor Sharpening, Hair Cutting Scissors, and Stellite

THERE'S NOTHING LIKE A GREAT PAIR OF HAIR CUTTING SCISSORS IN THE HANDS OF A GOOD STYLIST THAT WERE SHARPENED BY A GREAT SCISSOR SHARPENER! www.xzactashears.com The following was emailed to me from "MisterD" in response to questions about Stellite.
Stellite alloy is a range of cobalt-chromium alloys designed for wear resistance. It may also contain tungsten and a small but important amount of carbon. It is a trademarked name of the Deloro Stellite Company and was invented by Elwood Haynes[1] in the early 1900s as a substitute for flatware that stained (or that had to be constantly cleaned).PropertiesStellite alloy is a completely non-magnetic and non-corrosive cobalt alloy. There are a number of Stellite alloys, with various compositions optimized for different uses. Information is available from the manufacturer, Deloro Stellite, outlining the composition of a number of Stellite alloys and their intended applications. The alloy currently most suited for cutting tools, for example, is Stellite 100, because this alloy is quite hard, maintains a good cutting edge even at high temperature, and resists hardening and annealing due to heat. Other alloys are formulated to maximize combinations of wear resistance, corrosion resistance, or ability to withstand extreme temperatures.Stellite alloys display astounding hardness and toughness, and are also usually very resistant to corrosion. Stellite alloys are so hard that they are very difficult to machine, and anything made from them is, as a result, very expensive. Typically a Stellite part will be very precisely cast so that only minimal machining will be necessary. Machining of Stellite is more often done by grinding, rather than by cutting. Stellite alloys also tend to have extremely high melting points due to the cobalt and chromium content.Stellite has also been used in the manufacture of turning tools for lathes. With the introduction and improvements in tipped tools it is not used as often any more, but it was found to have superior cutting properties compared to the early carbon steel tools and even some high speed steel tools, especially against difficult materials such as stainless steel. Care was needed in grinding the blanks and these were marked at one end to show the correct orientation, without which the cutting edge could chip prematurely.Compliments of the EdgeWalker and Wikipedia online dictionary. See how easy it is to learn .For scissors manufacturing I look for a factory using the term "wire cut". This usually means they use a spark machine [old term] Today its call EDM forming machine. [electric discharge machine] Using computerized software the EDM machine can cut extremely intricate designs through the hardest alloys while the metal is in its harden state. EDM produces no damaging heat while cutting, leaves no burrs and requires no finishing. A process of this nature provides an excellent method of exact duplication and quality control. This process can eliminate heat treatment and forging processes. Production of a scissor or texturizer not subject to frequent alterations are good uses for this technology.Compliments of the EdgeWalker and Wikipedia.
