How to Become a Sharpner

The sharpening machine used by Katana Edge was invented fifty years ago in Japan. Since then, it has been improved upon numerous times in an effort to create the most superior and precise sharpening machine in the world. It is believed that the current machine, version 5, is the most superior sharpening product ever made in Japan. Now, more than 60,000 machines have been produced and their reputation and popularity have spread among stylists and sharpeners in Japan.

The Correct Way to Sharpen

We sharpen your shears according to which type of blade you have: a convex or a beveled blade.
We faithfully maintain on all shears the original factory edge. If your edge has been altered from a convex edge to a beveled edge, we can restore it completely. 





Why The Katana Edge Method is Superior

Bevel Edge vs. Convex Edge

The machine is designed to perfectly sharpen both bevel edge and convex edge shears. Most Japanese shears have a unique blade shape called hamaguri (clam shell or convex edge). It isn't easy to find a sharpener who can sharpen your shears and maintain the shear's factory edge. When attempting to sharpen shears, most sharpeners do so by making a bevel edge on the blade. They alter the angle of the blade resulting in damage to the shears. Creating a bevel edge on a convex-edge blade means the blade will then slide the hair toward the tip of the shears rather than cutting the hair at the intended location on the blade. Scissors are valuable and often expensive, so it is imperative they be sharpened correctly in order to maintain the integrity of the blades and to lengthen the life of the shears.

A Perfect Match for Radius 800

The Japanese precision shear has a radius of 800 millimeters on its edge line as pictured below. The machine is perfectly designed to match this shear’s structure. By placing the shear on the sharpening machine (held in place by a bracket) and by making a back-and-forth movement against the sharpening disks, the blade is automatically sharpened at a radius of 800 millimeters.

Ideal Size

The machine is small and light. You can carry the machine anywhere by hand. That’s right, the machine may be operated at a stylist’s station, a back room, or in any small space. Many stylists welcome on-site sharpening and it saves both the sharpener and the stylist valuable time.

Maintains the Factory Edge

The edge of the blade is invariably diminished during sharpening. However, reducing the materials on the edge results in a shorter life for shears. The machine has solved this problem. Fragments of diamonds or diamond powder have been applied to the disks used in sharpening and buffing with the machine. Thus, the materials on the blade remain largely intact. Most other sharpening methods involve the use of a grinding stone that may result in the destruction of the materials on the blade and shortening the life of the shears.
