KASHO handcrafted Professional Stylist Shears are the crowning achievement of the “shisho”, a highly skilled craftsman who proudly engraves his shears with the KASHO mark. Each pair of KASHO shears reflects impeccable form, finish and function. Today, every pair of KASHO shears is created through careful design and engineering with advanced materials and heat-treatment technology – and the blending of an integrated manufacturing process with skillful workmanship which measures up to the unrelenting standards passed through generations of the Japanese Samurai sword smithies.
KASHO shears are manufactured from a special high-carbon stainless steel alloy, which has superior resistance to corrosion and wear. The steel is variously compounded with Molybdenum, vanadium, cobalt and other elements to achieve state-of-the-art characteristics. KASHO’s advanced heat treatment and sub-zero quench techniques assure long-term blade sharpness and durability.
The unique manufacturing process ensures the necessary precision of the concave inner surfaces (hollow ground) and convex outer surfaces of the shear blades. The convex-edged shear blades are characterized by their exceptionally durable cutting edge. These blades are honed to an extremely sharp state with the inner side hollowed to such a point that the blades only touch at the point of intersection. This refined technology ensures superb cutting edge durability, while at the same time reducing cutting edge resistance to a minimum – and thus considerably reducing hand fatigue.
Kasho has developed a computerized grinding machine with laser sensors to guide the blade through the hollow grinding process – thus assuring absolute accuracy in shaping the proper curvature of both the inner concave blade surface and the exterior convex surface.
Every surface is hand polished to a flawless mirror finish. Top and bottom blades are selected, and then hand-worked until they become a perfect matching set. They are meticulously hand-honed, assembled, and set by a “Shujin” master, in a laborious, time-consuming process and finished to his own exacting standards. Taken together, these elements represent the highest expression of hair shear technology and craftsmanship.
