Kashoカショー

Most stylists meet Kasho without quite knowing they have. The name belongs to KAI Corporation, the same Japanese firm that makes the razor blades in your bathroom and a good chunk of the kitchen knives in Japan. KAI has been forging steel since 1908, and Kasho is the slice of that empire pointed squarely at hairdressers.

That heritage isn’t marketing varnish. KAI grinds its shears in Seki City, Gifu — a blade town with a 700-year sword-smithing tradition behind it — and the company turns out more than 10,000 different cutting products. When you buy a Kasho, you’re buying into industrial muscle that a small artisan workshop simply can’t match. That’s the brand’s whole personality, for better and worse.

How they’re made

Kasho’s signature is the Ultimate Edge, a dual-alloy blade. Rather than grind one steel into a shear, Kasho works two stainless grades of different hardness into the same blade. The steel is compounded with molybdenum, vanadium, manganese and boron, hot-forged, then triple-tempered through an isothermal process that reorders the grain without giving up the alloy’s character.

The geometry matters as much as the metal. Kasho uses a convex hollow-ground blade: the inner face is concave, the outer face convex, both shaped by a computer-guided grinder with laser sensors. The two blades only kiss at the exact point of intersection, which is what gives a Kasho its quiet, low-drag cutting feel. Every surface is then hand-polished to a mirror, and a master finisher — KAI calls him the Shujin — sets the final tension by hand.

The steel worth knowing

The workhorse alloy is VG-10W, a tungsten-enhanced VG-10 from Takefu Special Steel. The tungsten precipitates fine, hard carbides; Takefu claims roughly 20% better durability and 25% better cutting performance than standard VG-10. At HRC 59–61 you can expect six to ten weeks between sharpenings at a normal salon pace, and the convex edge copes happily with both wet and dry cutting.

Climb the range and you reach ATS-314 cobalt alloy and, at the top, the Millennium series built on SG2 sintered (powder-metal) steel. Powder metallurgy compresses and heats the metal below its melting point, producing a finer grain than cast steel can — a sharper, longer-lasting edge for stylists who cut all day.

The lines worth knowing

The Millennium and XP shears carry Kasho’s patented Disc Operation System, a tension dial that holds its setting far better than a plain pivot screw over months of use.

Who should buy Kasho

This is a shear for the mid-career stylist who cuts a bit of everything and wants proven VG-10 performance without paying artisan prices. The KAI backing means you can get it sharpened anywhere, find parts in most markets, and not worry that the maker will vanish. It’s also a sensible choice for salon owners who want consistency across several chairs.

Where it stops short is the specialist end. If you’re a dedicated slide-cutter or you crave the very hardest cobalt and powder-metal edges, you’ll eventually look at Joewell’s cobalt lines or the razor-bred geometry of Kamisori. Kasho is honest about being the dependable middle — and after a century of grinding steel, it has earned the right to be.
