The Xzacta Shears Ride Honing Plate
“scissor sharpening with a curve”

The Ride Honing Plate was developed after years of frustration with trying to hone the “curved” ride portion of scissor blades with flat “stones”. The physics of this is simple…. It doesn’t work well!

When I first came up with the idea of a stone, glass, or metal plate with a curvature to match that of the curvature of a scissor blade (commonly called the set), I spent well over a week trying to make this by hand. The curvature is so slight that I kept getting multiple flat spots, so I gave up and went to my machinist. After a complicated mathematical formula, some prototypes, some educated guessing, perseverance, and a little luck, we were ready for production.

It takes nearly three hours to machine just one, and of course it has to be done, like anything in a machine shop, in quantity to make it affordable.

There are several key factors to the success of the Ride Honing Plate.
1. The other scissor or shears sharpening processes must be done correctly.
2. The Ride Lines on many if not most scissors are done incorrectly at the factory. Many factory ride lines are too wide with way to much angle on the ride line. The ride line, to function properly, should be thin with a “microscopic” angle. This is so the cutting edges come very close to engaging, but never touch. Too much factory angle, and the hair cutting will feel crunchy even though the blades may be razor sharp. Xzacta Technicians are taught to correct this in successive sharpenings, usually about three. To correct this in one scissor sharpening would tremendously decrease the serviceable life of the shears. If the shears have to much factory angle, you will be polishing on the portion of the ride line closest to the hollow grind without ever coming close to the cutting edge. Corrective procedures for this are taught in class and not covered here. They are just too delicate.
When the ride line is “sweet” (proper), the Xzacta Shears Ride Honing Plate will deliver a mirror-like polish to the entire ride line with a microscopic angle. The microscopic angle is developed because the blade slightly sinks into the micron film. Xzacta uses water to attach the film because it allows for more cushioning than that of a psa attachment. The results are outstanding.
3. In the real world of scissor sharpening, the Xzacta Shears Scissor Sharpening Techs don’t see a lot of new scissors or shears. What we see are shear after shear of improperly sharpened or “destroyed” shears ….the by-products of grinders, as well as many flat honers. Many, many of our so-called competitors do not take the scissors apart to sharpen and do nothing at all to the ride line other than maybe a swipe across their jeans to try and remove a little burr. It is just incomprehensible! In fact many times there will be absolutely no ride line left. If they do take them apart, then they use a curved blade on a flat honing stone to attempt to re-establish a ride line. The results at best are poor, resulting in over-worked tips, and a “flat” ride line if they actually did establish one. The flat ride line will result in the cutting edges making direct contact which dulls the edges very quickly or folds the cutting edge over if it doesn’t break out, …and worse yet…nicking.
The “sweet” honing of the ride line is possibly the most important step in the scissor sharpening process. If you do this part incorrectly, it really doesn’t matter what kind of machine you’re using.
The Xzacta Shears Ride Honing Plate will gently re-establish a non-existent ride line with mirror finish and the very important microscopic angle. The results are nothing short of superb when combined with the Xzacta Shears Ultimate Scissor Sharpening Machines, Systems, and Training. However, the Ride Honing Plate will increase the quality of your scissor sharpening even if you are using a competitor’s scissors sharpening machines. This is just light-years ahead of the conventional flat honing stones that are traditional in the scissor sharpening industry.

AISI Scissor Stainless Steel

AISI stands for American Iron and Steel Institute. There are other standards for metal used in scissors and shears as well as all other applications. SAE stands for Society of Automobile Engineers. SNS stands for Simplified Numbering System. There are other international standards. If I am incorrect, please correct me.
We were addressing a question of AISI 440C as far as damage to shears or scissors if they incurred all the possible damage previously mentioned.
No, I do not have direct consequences to damage that is specifically detetermined to be AISI 440C Stainless Steel.

Scissor Sharpening Hair Cutting Scissors Shears for the Progessional Scissor Sharpener

AISI 440 C Stainless Steel ? This is a question to professional Scissors/Shears Sharpeners. If you know for sure that a pair of scissors is AISI 440 C, what is your experience with the degree of damage when scissors 1. dropped on a concrete floor 2. thrown at another hair stylist 3. thrown at the salon owner 4. dropped right on the tips of a clients big toe??

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.
