Scissor Sharpening Industry Standards

Corner Beauty SalonTo understand what sharpening equipment is needed, you need to understand the scissors you will be sharpening. The most lucrative segment of the scissor sharpening industry is the beauty segment - beauty salons and barbershops seem to be on every street corner and in between as well. Do you own search scientifically by counting the listings in the Yellow Pages, or just drive down the streets of your community.

While it is hard to get an accurate account, because beauty businesses open, close and move like any other business group. But the most reliable sources, the US government reports 86,000 beauty salons and barbershops in 2012 with gross revenues of more than $20 billion dollars. A national list service provides contact information for more than 450,000 beauty salons and barbershops in the same time period. Which is correct? We don't know, we do know that a properly served area of 300 salons can provide an income level equal to or above the top 10% of occupations in the USA today.

Most of the stylists currently use what is referred to as the "Japanese Style" hair cutting scissors. This style of shear has four distinct features:

Each feature provides a specific function to provide the best cutting experience for the professional stylist, barber or haircutter. The sharpening equipment you choose must allow you to address each feature or you will inadvertently damage or destroy the ability of the scissors to do the job intended for the professional using them.

The Hollow-ground - ride area -

Hollow Ground interior of scissor bladeThe Japanese style haircutting scissors are intentionally hollow ground on the inside of the blade to create a "ride area." This ride in conjunction with the convex edge creates a nearly razor sharp cutting surface designed to give the scissors a cleaner/sharper cut. The stylist appreciates the smooth action of the Japanese style shear and the ease of cutting it provides when cutting hair. This combination of ride and convex edge also allows a cutting technique the stylist refer to as "slide cutting."

The Convex Edge

convex cutting edgeThe convex edge is one of the most important components of the Japanese style hair cutting shear. It is largely responsible for the smooth cut the professional hair cutter desires. This is where one of the biggest problems begins. a "grinder" style sharpening machine will absolutely ruin the Japanese style shear by destroying the convex edge and replacing it with a bevel "concave" edge. A convex grinding wheel can only make a concave edge on the shear blade. Don't let anyone try to tell you different. Convex clamps or multiple concave edges do not, no can not create a convex edge. If you want to save money by purchasing a grinder, stay out of the beauty salons! Most of the stylists have for years used, and now, even the barbers and some dog groomers are switching to the Japanese style shear. Sharpening a $600.00 Japanese style shear on a grinder will cause it to cut exactly the same as a pair of low end $50 to $75 dollar barber scissors. Please do not ruin your customer's scissors. Invest in the right equipment to do the best job possible.

800 Millimeter Radius

800 millimeter radiusThe 800 millimeter radius is that slight curve from the hilt to the tip on a Japanese style hair cutting shear. It is designed to "hold" the hair in place when the operator cuts through a section of hair. This curve in the blade adjusts the angle of attract as the blades close on the hair and make them grab and cut sooner rather than later. Prior to the Japanese style shear invention this was accomplished by putting a serrated edge on one blade of the German style barber scissors. The hair caught in the small grooves in one blade allowing the other blade to cut the hair. The issue with this arrangement was in two areas. One, it was a noisy rough cut and two, it was was not possible to use the popular "slide cutting" technique. The blade caught and pulled the hair instead of making the smooth cut of the Japanese style hair cutting scissors.

The "Set"

The SetThe set in the blade causes the shears to maintain a constant pressure from the hilt to the tip as the shears close. The set is critical to the function of the shear. If it is not precise the scissors will not cut properly. The terms "set" and "torque" can almost be used interchangable when discussing how the scissors blade closes.

You have experienced the "torque" application when trying to cut with dull scissors or trying to cut through either too thick or too much in volume. The scissors were not cutting so you "torqued" the blade to make them close tighter, thereby forcing the blades to cut through the material.

And therein is a huge problem in the sharpening industry. Many people and even sharpening machine manufacturing companies propose "adjusting the set" by that they mean bend the blade so the scissors will cut. This "bending" of the blade they suggest puts a constant torgue on the scissors. It is used as a substute for quality sharpening. Our experience proves that if the scissors are sharpened with precision such as that found with the Diamond Rose Superior Sharpening System, "adjusting the set" is not necessary.

In those few ocassions where a pair of scissors has been bent so that it needs the set adjusted, it needs special attention to assure a consistent bend is applied to the entire blade. Putting a scissor blade in a plastic groove and bending at will risks breaking the blade and is highly unlikely to yeild a "set" matching the factory specs on the shear.
