Description
The togishi is the Japanese trade of scissor restoration: edge, set, hollow and parts treated as one system, with maker programs and service limits.
The Togishi Craft (研ぎ師 - Togishi)
The togishi (研ぎ師) is the Japanese trade of professional scissor restoration: a sharpener who treats the tool as a complete mechanical system, covering the edge, the blade set and alignment, the hollow inner grind, and the replaceable parts, rather than refreshing an edge alone. The term translates as “sharpening master.”
Quick look
- What it is: Professional scissor restoration as a Japanese trade, beyond basic edge sharpening
- Japanese term: 研ぎ師 (togishi), “sharpening master”
- Scope: Edge work, structural correction, parts replacement and adjustment as a package
- Key distinction: A togishi works to the tool’s designed geometry rather than to a fixed sharpening angle
What togishi work includes
The togishi discipline encompasses a full range of restoration services that go well beyond edge sharpening:
| Service | Japanese | Description |
|---|---|---|
| Edge grinding | 刃付け (hatsuke) | Restoring the primary cutting edge to factory geometry |
| Chip repair | 刃こぼれ修理 (hakobore shūri) | Removing nicks and chips without excessive metal loss |
| Warp/bow correction | 反り矯正 (sori kyōsei) | Straightening blades that have bent or twisted |
| Tip adjustment | 先詰め (sakizume) | Correcting tip alignment for clean point cutting |
| Parts replacement | 部品交換 (buhin kōkan) | Replacing bumpers, finger rests, tension screws, and pivot components |
A togishi evaluates the entire scissor as a system—not just the edge. Blade alignment, tension mechanism condition, pivot wear, and handle ergonomics are all part of the assessment.
Key practitioners and networks
Scissors Yamato (シザーズ大和): Specialist in urasuki (裏すき / inner concavity) restoration—the hollow-ground interior of convex blades. Urasuki geometry is critical to how convex scissors cut, and improper sharpening can destroy it. Scissors Yamato is recognized for precision work on high-end Japanese scissors.
Hikari Factory Service: Hikari (株式会社ヒカリ) offers factory sharpening and restoration for their own scissors, maintaining the original hamaguri-ba radius through their in-house togishi. Hikari warns that non-manufacturer sharpening can permanently destroy the designed edge profile.
HSC: A Japanese sharpening column published under the HSC name explains why makers prefer to service their own scissors rather than send them to independent sharpeners. The repo records two different expansions of that acronym, “Hairdressing Scissors Consortium” and “Hasami Safety Cooperation,” and whether they are one organization or two sharing initials is unresolved, so this page does not state which.
Bitsuhan (美通販): A Japanese beauty-supply referral channel that connects stylists with sharpening services and maintenance resources.
Mizutani Certified Sharpener Program
Mizutani Scissors (ミズタニシザーズ) created the first international scissor sharpener certification program by a Japanese manufacturer. The program requires training at the Mizutani Factory in Chiba Prefecture, where sharpeners learn to maintain Mizutani’s specific blade geometries and quality standards.
Mizutani maintains an exclusive service policy: “If they did not make them, they will not fix them.” Mizutani factory service and their certified sharpener network only accept Mizutani scissors. This policy reflects the company’s position that each manufacturer’s blade geometry requires specialized knowledge to maintain correctly.
Why togishi-level service matters
Sharpening removes material, so work that does not respect the model’s geometry spends the tool’s remaining service margin. A togishi-level service:
- Works to the maker’s designed cutting geometry, including the hollow inner grind
- Assesses the pivot, tension mechanism and parts as part of the same job
- Explains what was removed and what has changed in the cutting feel
If your scissors have a convex edge, they need a method that preserves the convex profile, not a process that flattens it into a bevel.

Sources and limits
The service scope and the maker programs described here are the inherited sources’ account of one trade and its networks. Mizutani’s certification program and exclusive service policy, Hikari’s in-house service and its warning about non-manufacturer sharpening, and the Scissors Yamato urasuki specialization are all maker- or business-specific statements, not a ranking of independent sharpeners. No source located for this page establishes how often a scissor needs professional service, how many sharpening cycles a given tool supports, or that maintenance rather than use accounts for most damage over a career; service the tool when verified performance changes and follow the maker’s guidance.

Frequently Asked Questions
3 answers you can open one at a timeHow does togishi work differ from ordinary sharpening?
A togishi (研ぎ師) treats the scissor as a complete mechanical system rather than just an edge. The scope covers edge grinding (hatsuke), chip repair (hakobore shūri), warp and bow correction (sori kyōsei), tip adjustment (sakizume), and replacement of bumpers, finger rests, tension screws, and pivot components. The togishi evaluates blade alignment, tension mechanism condition, pivot wear, and handle ergonomics, then works to restore the scissor’s designed performance rather than only its edge.
What is Mizutani's 'If they did not make them, they will not fix them' policy?
Mizutani Scissors maintains an exclusive service policy: its factory service and the certified sharpener network it trained accept Mizutani scissors only. Mizutani runs the first international scissor sharpener certification program by a Japanese manufacturer, with training at its factory in Chiba Prefecture. The policy reflects Mizutani’s stated position that each maker’s blade geometry needs specific knowledge to maintain correctly.
When should a stylist seek togishi service instead of machine sharpening?
Choose togishi service when the scissor has a convex or hollow-ground edge you want to keep, or needs more than an edge: chip repair, warp correction, or tip or pivot work. Machine work is documented for flat bevels and can trade the maker’s geometry for speed. A maker’s own service route is a third option, and its terms decide what it accepts.
