Introduction
Kasho is the professional shear division of the KAI Group—the same Japanese company known for surgical blades and Shun knives. That manufacturing muscle translates into repeatable quality, thoughtful ergonomics, and pricing that undercuts boutique brands. The appeal is simple: predictable performance and easy servicing. I’m not a reseller; this profile is here so you can decide if Kasho aligns with your workload and budget.
Heritage & Manufacturing
Kasho’s story began in Seki over a century ago. While the brand leverages modern CNC machining, final grinding and finishing still happen by hand. Forging takes place in KAI’s controlled facilities where temperatures and cooling cycles are monitored digitally. Blanks are tempered twice to stabilise the steel. Edges are ground using a combination of diamond wheels and hand-held water stones, then polished to a mirror. Quality control is strict: each pair is laser-measured for symmetry and tension-tested before boxing. Because the KAI Group also produces surgical instruments, Kasho benefits from clean-room assembly spaces, reducing contaminants that can scratch blades early in life.
Technology & Materials
Kasho primarily uses VG-10W and ATS-314 cobalt alloys. VG-10W introduces tungsten for extra wear resistance, while ATS-314 keeps things light and balanced. The convex blades are paired with a hollow-ground inner face, delivering sharpness without sacrificing strength. Many series use the Disc Operation System — a sealed pivot with a disc spring that maintains tension and minimises the need for constant adjustment. Handle options include straight, offset, and semi-offset, each with a slim thumb to reduce over-extension. The XP Series introduces a removable finger rest and subtle texturing on the shank for better grip when hands are damp.
Standout Features
- Disc Operation System: Keeps the feel consistent even after months of daily use.
- Mirrored ride lines: Reduce drag during scissor-over-comb work.
- Integrated stopper: Cushions the close, lowering vibration transmitted to the hand.
Model Range
| Series | Use Case | Sizes | Notes |
|---|---|---|---|
| Green Series | Everyday salon work | 5.0”-6.5” | Straightforward offset ergonomics, great starter premium pair |
| Millennium | High-end precision cutting | 5.5”-6.5” | DLC coating option, hand-finished in limited batches |
| XP Series | Versatile all-rounder | 5.0”-7.0” | Disc Operation pivot and slightly heavier spine for durability |
| Silver Series | Entry premium | 5.5”-6.5” | Semi-offset handle, affordable path into Kasho |
Texturising options span 15 to 38 teeth. Kasho also produces left-handed variants in the Green and Millennium lines, maintaining the same grind rather than flipping blades. Australian distributors typically stock Green, XP, and Silver, with Millennium arriving on request.
Professional Fit
- Salon teams: Green Series hits the sweet spot between price, durability, and feel.
- Advanced stylists: Millennium offers boutique finishing without leaving the KAI support ecosystem.
- Barbers: XP Series has the spine strength for scissor-over-comb and taper work.
- Apprentice mentors: Pair Silver texturisers with cutting shears to practice weight removal without tearing.
If you crave ultra-soft glide for dry cutting, consider Hikari. If you need more flamboyant styling, Kamisori may suit. Kasho thrives when you want premium consistency and access to national servicing.
Maintenance Requirements
Wipe the blades after each service and oil daily. The Disc Operation System prefers light tension—over-tightening shortens spring life—so note your ideal drop-test angle and reset it after travel. When performance dips, book a technician familiar with the disc system; the spring stack needs to go back in a specific order. Keep chemicals away from the pivot; if colour or bleach seeps in, flush with warm water, dry thoroughly, and re-oil.
Authenticity Verification
Every Kasho shear ships with a red presentation case, warranty leaflet, and serial number etched near the screw. Scan the QR code inside the booklet to register within 30 days. Genuine pairs include an authenticity hologram on the case and a steel-spec card. Counterfeits often misspell “Kasho” or use screws without the signature red insert. Buying second-hand? Request proof of purchase or previous service receipts and run through the authenticity checklist before committing.
