Sasa-ba (笹刃) Blade Line
Blade linesA line name needs a maker, plane, radius basis, and zone
The same Japanese or translated label can cover different radii and intended uses across makers. Apply to Sasa-ba (笹刃) Blade Line
- 01 Wording Keep the source language, maker, model, market, and date.
- 02 Measurement Record radius with blade or chord length and measurement basis.
- 03 Scope Identify uniform or zoned curve and plan or vertical plane.
- 04 Context Add section, edge, width, pairing, and maker-stated use.

Description
Sasa-ba is bamboo-leaf vocabulary used in scissor catalogues. Verify the exact model's line or plan form, view, dimensions, section, edge, use statement, and service route.
Sasa-ba (笹刃) — bamboo-leaf wording
Sasa-ba combines Japanese wording associated with “bamboo leaf” and “blade.” In scissor catalogues, the term can cue a line or plan form, but its precise scope remains maker- and model-specific.
Do not turn the leaf metaphor into a fixed curve, radius band, width distribution, technique score, or position in a universal hierarchy.
What the term establishes
| Supported cue | What remains open |
|---|---|
| The cited source uses bamboo-leaf wording | Exact line, width distribution, radius, tolerance, and measured zone |
| The maker attaches the term to a named model or range | Whether it denotes line, plan form, family, or combined construction |
| A fuller or curved form may be shown in an exact drawing | Body cross-section, final edge, inner relief, and partner blade |
| The maker may publish an intended use for an exact model | Universal technique result, hair-type match, user level, or quality rank |
A catalogue photograph without a declared view and scale cannot establish precise curvature or width.
Keep the other geometry fields separate
- Blade line: heel-to-tip path in a declared side or plan view.
- Body cross-section: end-on form of each blade half.
- Edge or grind: the maker-stated working surface, finish, honing, or serration.
- Inner geometry: relief, hollowing, contact lands, pairing, set, and current condition.
Sasa-ba cannot determine any field that the exact source leaves unstated.
Compare sasa-ba with another model
Capture:
- maker, model, code, size, handed variant, market, and source date;
- original term and maker-supplied translation;
- declared view, blade orientation, heel and tip datums, and measured zone;
- drawing, coordinates, sagitta, radius, or width measurements with their basis;
- section, edge, finish, inner relief, partner blade, and pivot;
- maker-stated use and limitations; and
- condition, service history, trial, return, warranty, and service terms.
Do not infer that every sasa-ba is more or less curved than every yanagi-ba, or that two sizes under one family name share identical geometry.
Trial the complete shear
A maker or specialist source may discuss sasa-ba in relation to a technique. Treat that as a scoped statement, not a guarantee. Observe the exact tool, user, task, practice material, condition, and session.
Record control, push, fold, drag, effort, noise, and repeatability without diagnosing the cause from the line name alone.
Service boundary
Sasa-ba does not prescribe a lighter tension, wheel, stone, abrasive, sharpening direction, or service interval. Ask how the provider will identify and preserve the exact model’s line, width, section, edge, inner relief, pairing, and set, and document the work completed.

Frequently Asked Questions
3 answers you can open one at a timeWhat does sasa-ba mean in a scissor catalogue?
Sasa-ba (笹刃) is commonly translated as bamboo-leaf blade. Depending on the maker, it may label a line, plan form, width pattern, model family, or combined construction. Preserve the source’s exact scope.
Is sasa-ba always more curved than yanagi-ba?
No universal order should be assumed. Compare exact-model drawings or measurements made from the same view, measurement zone, size, and radius or coordinate basis.
Does sasa-ba require a particular technique or sharpening method?
No universal use or service prescription follows from the name. Follow the exact maker’s stated use and care instructions, trial the complete model under controlled conditions, and use a provider qualified to preserve its documented geometry.
