Blade Types
Separate the four blade fields that labels often collapse
A named blade type can combine line, section, edge, and pairing; record each field before comparing. Apply to Blade Types
- 01 Line Record plan-view line, any radius, zones, and measurement basis.
- 02 Section Describe each blade half rather than assuming a universal profile.
- 03 Edge Keep grind, finish, honing, and serration separate.
- 04 Pairing Attach asymmetry and intended use to the exact model.
Do not inferA translated name, side photograph, silhouette, or one radius cannot prove the full geometry or predict performance.
A blade name is not a complete geometry
Start with the named blade family, then record its line, end-on section, final edge, and viewpoint independently.
-
01 Side / plan view Source-scoped
Blade line
Blade-family names may point toward a longitudinal profile.
Leave openExact curve, measured zone, width, and heel-to-tip transition remain model-specific.
The route supports this vocabulary, within the cited source boundary.
-
02 End-on slice Open field
Cross-section
Sword, standard, willow, and similar names do not fix one end-on section.
Leave openRidge, thickness, hollowing, and which blade carries a feature remain open.
This route does not settle the field; record it separately.
-
03 Magnified working edge Open field
Edge / grind
The final working edge must be read from its own specification.
Leave openConvex, flat facet, finish, serration, and service construction remain open.
This route does not settle the field; record it separately.
-
04 Declared axis + view Open field
Spatial curve
Compare models from the same declared side or plan view.
Leave openCamera angle, scale, blade half, and curvature datum remain open.
This route does not settle the field; record it separately.
Blade-family names are catalogue clues, not complete engineering specifications. A name may describe the heel-to-tip line, the end-on section, reinforcement along part of the blade, or several features at once. Keep the maker’s wording attached to the exact model and dated source.
Blade vs Edge (Critical Distinction)
- Blade type: maker or trade vocabulary that may point to a line, section, width pattern, reinforcement, or combined construction.
- Edge type: wording for the final working surface near the cutting edge, including rounded, faceted, polished, or serrated features.
Neither label ranks sharpness, force, glide, durability, user level, hair match, or technique by itself. A single blade-family name can appear with different sections and edges.
How to Use This Guide
- Capture the exact maker, model, catalogue wording, and dated source.
- Record the side-view blade line, end-on section, final edge and finish, and the viewpoint for each drawing or photograph.
- Add dimensions, partner blade, condition, maker-stated use, and service route without filling gaps from the family name.
- Trial the complete model in the intended task; keep the observed result attached to that setup and hair state.
Tags reproduce broad catalogue-use labels for navigation. They are not a ranking or prescription; verify the exact model, complete geometry, condition, and maker-stated use.
Quick recording prompts
- The silhouette looks straight or curved: label the side or plan view, measured zone, and exact model before naming the line family.
- A ridge or fuller body is visible: add an end-on section and show which blade carries it and how far it extends.
- The working edge looks rounded, flat, polished, or toothed: record that as a separate edge and finish field.
Common blade designs
- Standard, classic, or narrow: broad catalogue terms; ask for the actual line, width, section, and edge.
- Wide or power: relative width wording; ask where width is measured and which comparison model supplies the baseline.
- Sword or partial sword: look for a maker drawing of the ridge, section, blade half, and heel-to-tip extent.
- Clam shell or convex pro: preserve the maker-local term and establish whether it describes section, outer grind, or both.
- Serrated or micro-serrated: record tooth pitch, depth, profile, blade side, host grind, partner blade, and scale.
Choosing by technique
Do not choose a model from the family label alone. Shortlist exact models using the maker’s published construction and intended use, then compare fit, control, condition, and observed result in the real task. Leave any unpublished line radius, section dimension, edge angle, or performance claim unknown.

Frequently asked questions
Sword vs bamboo-leaf—when should I pick each? First verify what each maker means. Sword usually prompts a ridge or reinforced-section check; bamboo-leaf usually prompts a fuller side-view line check. Compare the complete named models, their documented use, and your controlled trial instead of treating either label as a technique guarantee.
Can I mix any blade type with any edge? Do not assume every pairing exists or can be created safely. Use only the exact construction published for the model, and follow its maker or qualified service route rather than specifying a regrind from two category names.
Do longer blades always cut faster? No. Nominal length does not establish removal per stroke, control, or technique. Record how the maker measures length, the pivot-to-tip reach, blade width and line, section, edge, balance, condition, and the observed task result.

4 answers you can open one at a timeWhat is the difference between blade type and edge type?
Blade type is catalogue vocabulary that may refer to line, width, reinforcement, section, or more than one feature. Edge type describes the final working surface near the cutting edge. Neither term establishes cutting behavior alone, so record the exact model’s line, section, edge, finish, pairing, and maker-stated use separately.
Which blade profiles suit slide and point work?
No blade-family name guarantees a technique result. Use the maker’s exact-model use statement, line drawing, section, edge, condition, and a controlled trial in the intended task. The willow blade and bamboo-leaf blade entries are vocabulary starting points.
What blade shape gives the most power for blunt cutting?
A family name cannot rank cutting force. Compare exact-model dimensions, section and pairing, edge and finish, tension, condition, maker evidence, and the intended section. A sword blade label is a prompt to verify the ridge or reinforcement, not a power score.
Are narrow blades better for detail cutting?
Not from width alone. Blade length, width distribution, tip form, line, section, edge, balance, handle, condition, and the operator’s control all matter. Compare named models and test the complete shear rather than prescribing an edge from a narrow-blade label.
