K-Blade
Edge typesKeep the edge term attached to geometry and service
An edge label becomes useful only when its maker wording, host blade, finish, and service route are known. Apply to K-Blade
- 01 Record the term Preserve the exact maker and model wording.
- 02 Locate the edge Identify the blade half, section, line, and any serration.
- 03 Trace its condition Keep sharpening, damage, coating, and inspection history.
- 04 Choose service Ask how the provider will preserve the original geometry.
Do not inferPolish, shine, feel, or a marketing label cannot diagnose an edge geometry or authorise a sharpening method.
K-Blade has no safe axis until the maker defines it
The name may point to line, section, outer curve, or another feature. The recorder leaves every unsupported axis visibly open.
-
01 Side / plan view Unresolved
Blade line
The name does not prove a plan-view blade line.
Leave openHeel-to-tip curve, radius, transition, and width remain unknown.
The available label does not reveal the geometry or measurement axis.
-
02 End-on slice Unresolved
Cross-section
The name does not prove an end-on body profile.
Leave openRidge, thickness, hollowing, symmetry, and partner blade remain unknown.
The available label does not reveal the geometry or measurement axis.

03 Magnified working edge Maker-local
Edge / grind
Published wording may describe an outer curve, but only inside that source.
Leave openExact radius, angle, edge finish, and service construction remain open.
Keep the term attached to the maker, model, language, and dated source.

04 Declared axis + view Unresolved
Spatial curve
The defining measurement axis is not carried by the letter K.
Leave openViewpoint, scale, zone, datum, and geometry said to vary remain unknown.
The available label does not reveal the geometry or measurement axis.
Description
K-Blade is maker- or seller-local vocabulary with unresolved geometry. Without an exact cross-section, plan-view diagram, radii, and measurement datums, the name cannot establish blade line, outer grind, performance, technique, or service.
K-Blade is an unresolved maker or seller term, not a verified cross-industry geometry class. Current records use radius and K-blade wording without the plan-view drawing, cross-section, numerical radii, measurement datums, or blade-pair specification needed to determine whether separate listings describe the same construction across brands or models.
What Is Known and Unknown
| Recorded observation | Still unresolved |
|---|---|
| Saki uses K-Blade as proprietary vocabulary in its range | What the K stands for |
| A Shisato Regency seller listing also uses K-blade wording | Whether the Shisato and Saki constructions are related |
| Radius language appears in inherited descriptions | Which plane or surface the radius measures |
| Product photography shows the overall shear | Plan-view curvature, cross-section, edge transition, and dimensions |
The main ambiguity is the geometry axis. One description can be read as a larger plan-view blade-line curve; another treats the term as an outer convex face or edge radius. Those are different specifications. Neither interpretation should be selected without a maker diagram and measurement basis.
Minimum Documentation
Before using K-Blade in a comparison, record:
- maker, full model, and dated source;
- the maker’s exact K-Blade wording;
- plan-view line drawing with blade or chord length;
- cross-section of each blade half;
- radius, units, location, and measurement datum;
- outer grind, inner relief, and final edge treatment; and
- maker-stated use and repair instructions.
Until that record exists, performance language about capture, release, force, stability, hair type, or technique remains maker or seller copy rather than a transferable geometry fact.
Product and Service Boundary
The Shisato seller listing is useful as a terminology lead, not proof of the geometry behind its K-blade wording. A technician should inspect and document the complete blade pair, then follow the exact maker’s repair specification. Do not choose a sharpening method from K-Blade or radius-edge wording alone.

Frequently Asked Questions
4 answers you can open one at a timeWhat geometry does K-Blade describe?
The available records do not resolve that question. Saki materials associate K-Blade with proprietary radius wording, while seller material for the Shisato Regency also uses K-blade language. No exact diagrams or shared datums establish whether those references describe plan-view blade line, outer cross-section, edge grind, or equivalent constructions.
Does "radius edge" define K-Blade?
No. A radius is incomplete without the measured plane, chord or blade length, location, units, and whether it is uniform or zoned. Calling K-Blade a radius edge does not identify which surface was measured or make two brands equivalent.
Does K-Blade guarantee hold, glide, or versatility?
No controlled or dimensioned evidence was found for universal performance. Keep any cutting-feel, hair-movement, technique, or material statement attached to the exact maker or seller page that publishes it.
How should a K-Blade be serviced?
First obtain the exact model’s maker diagram and repair specification. The label alone does not determine which face is curved, what profile must be preserved, or which abrasive, pressure, angle, and service interval are appropriate.
