VG-10 Steel: Takefu Data and Finished-Shear Evidence
Steel typesIllustrations are navigation markers, not technical evidence. They do not establish exact geometry, material identity, finish or coating identity and properties, adjustment settings, coating colour, hair classification, tooth pattern or removal rate, mechanism, fit, diagnosis, origin, performance, or result.
Read a steel claim as a four-layer record
A grade can be useful evidence, but a finished shear adds maker execution, geometry, condition, and service history. Apply to VG-10 Steel: Takefu Data and Finished-Shear Evidence

Description
VG-10 is a broad listing label. Takefu publishes representative composition and hardness data for its VG10 grade, while finished-shear claims need exact model evidence.
Short answer
This page uses VG-10 as its reader-facing label. Takefu Special Steel’s current English material page writes the exact grade as VG10. Its Japanese material page writes V金10 (VG10). Keep the wording from each source visible.
Takefu publishes a reliable public composition record for its own VG10 grade. The same page also gives a material-level hardness entry. Neither item certifies a blade or finished scissor simply because a catalogue uses a similar label.
Jaguar’s official KAMIYU page provides one exact finished-shear example. Jaguar describes KAMIYU as using VG10 cobalt steel from Japan and states 59 HRC. That is a maker statement for KAMIYU, not a universal specification for VG-10-labelled scissors.
Keep three evidence levels separate
| Evidence level | Record to keep | What it establishes | What it does not establish by itself |
|---|---|---|---|
| Broad listing label | The exact wording in a catalogue, listing, or maker page, such as VG-10, VG10, or VG10 cobalt steel | That the named source uses those words | Material producer, chemistry, batch, finished hardness, country of the whole scissor, or product performance |
| Documented material grade | Producer, exact designation, current producer page, product form, condition, and traceability record | The data within that document’s stated scope | Which material reached either blade of a finished scissor |
| Exact finished shear | Maker, model, variant, and current model page, plus material and finished-part records where published | Claims tied to that model or tested item | Facts about another model or every product carrying a similar steel label |
All three records can be useful. They answer different questions. Do not move a material value or a finished-model claim into a broader evidence level.
Takefu’s published VG10 composition
Takefu’s official VG10 page presents the following chemical-composition figures. Takefu calls them representative data for the standard values of the grade.
| Element | Symbol | Representative figure shown by Takefu |
|---|---|---|
| Carbon | C | 1.00 |
| Chromium | Cr | 15.00 |
| Molybdenum | Mo | 1.00 |
| Vanadium | V | 0.25 |
| Cobalt | Co | 1.55 |
The page’s prose expresses chromium as 15%, molybdenum as 1%, and cobalt as 1.5%. Its table does not print a unit or compositional basis beside every cell, so the table above reproduces the five figures without adding a basis that Takefu does not state.
These are not minimum and maximum limits. They are not a certificate for a supplied heat or lot. The page does not list manganese, silicon, phosphorus, sulfur, iron, or a balance entry. An element missing from this source should be left unreported, not filled from a seller chart or a different designation.
A reliable public composition can therefore be established for Takefu’s exact VG10 grade within this producer-page scope. A bare VG-10 listing still needs a traceable link to that material before the figures can be applied to a finished product.
What Takefu says about the material
Takefu says chromium, molybdenum, and cobalt strengthen the matrix. It says vanadium refines the microstructure, while chromium, molybdenum, and vanadium form hard carbides that improve wear resistance. The producer also describes its VG10 as corrosion resistant, machinable, and easy to sharpen.
These are Takefu’s material descriptions. The page does not publish a comparative test method, salon exposure protocol, cutting-life result, or sharpening interval. It lists kitchen knives, general-purpose knives, and machine blades as uses. It does not identify a finished hair scissor.
Takefu also asks buyers to make sure a product uses genuine VG10. That notice supports checking material identity. It does not identify any particular scissor brand or certify a listing.
Hardness without a universal scissor range
Takefu displays a value meaning HRC 60 or above in the hardness column on its VG10 material page. The Japanese version labels this as quench hardness. The public page gives no upper bound, test method, specimen condition, test location, or tolerance.
Jaguar gives a different kind of record. Its KAMIYU product page states 59 HRC for that finished hair scissor. The page presents the figure as Jaguar’s model specification. It does not turn the Takefu material entry into a finished-shear range, and the two figures should not be joined into one.
No universal HRC value is established for all products labelled VG-10. For an exact shear, ask whether the published value is a design target, an allowed range, or a measured result. Also ask for the tested blade, location, method, production scope, and tolerance.
One exact finished-shear record
| Field | Current maker statement |
|---|---|
| Maker and model | Jaguar KAMIYU |
| Material wording | VG10 cobalt steel from Japan |
| Hardness wording | 59 HRC |
| Evidence scope | Jaguar’s current model page |
Read this as a model-specific maker statement. It supports the material and hardness wording Jaguar publishes for KAMIYU. It does not certify another maker’s scissor, another model, a material heat or lot, or an independently measured result.
For purchase-specific traceability or testing records beyond the public page, use Jaguar’s official product route. Keep any reply with the exact model and variant record.
Keep VG10W separate
Takefu publishes VG10W on a separate official page and describes it as VG10 with tungsten added. The producer gives VG10W its own composition and hardness entries. This page therefore does not use VG10W as an alias for VG10 or transfer VG10W data into the VG10 table.
A shared name fragment does not prove that two designations, material records, or finished products are interchangeable. Preserve the exact wording in the source.
What the VG-10 label does not settle
The primary sources reviewed here do not establish universal finished-shear claims for:
- one HRC value or range across all makers and models;
- edge life measured in cuts, clients, weeks, months, or years;
- sharpening frequency, sharpening difficulty, or one required service method;
- corrosion performance under salon moisture, colour products, cleaners, or disinfectants;
- toughness, drop response, chipping, rolling, flex, or impact behaviour;
- country of melt, blade manufacture, assembly, or finished-product origin for an unidentified shear;
- price, value, market tier, or steel ranking;
- equivalence to another designation or maker label;
- blade weight, balance, feel, glide, technique suitability, or cutting performance; or
- superiority between finished scissors.
These are source boundaries, not findings about the quality of a named maker or model. Use each maker’s current statement within the product scope it identifies.
Checklist for an exact VG-10-labelled shear
| Check | Evidence to record |
|---|---|
| Product identity | Maker, model, variant, size, handedness, and sales region |
| Listing wording | The material label exactly as the source prints it |
| Material identity | Named producer and exact designation, with a direct producer document |
| Blade scope | Which blade parts the material statement covers |
| Traceability | Heat, lot, certificate, or written model-specific confirmation where available |
| Finished hardness | Value, scale, method, tested blade, location, status as target or result, production scope, and tolerance |
| Finished tool | Maker information for blade geometry, edge, pivot, tension, coating, and intended use |
| Ownership route | Current care, warranty, parts, and service information for the exact model and region |
If a listing only supplies the broad label, keep it at that level. Ask the maker for the missing product-specific record rather than filling gaps from another steel page.

Sources were checked on 22 July 2026. No retailer-generated steel guide, marketplace listing, generic comparison chart, unpublished test summary, or product photograph is used as technical authority. No image is displayed because an unrelated scissor photograph cannot establish material identity, composition, hardness, or performance.

Frequently Asked Questions
5 answers you can open one at a timeWhat does VG-10 mean on a scissor listing?
It records the wording used in that listing. It does not by itself identify Takefu as the material producer, certify either blade, or establish hardness, composition, origin, edge life, sharpening needs, or finished-shear performance. Ask for an exact maker and model statement.
Does Takefu publish a VG10 composition?
Yes. Takefu’s official VG10 page publishes representative chemical-composition figures for carbon, chromium, molybdenum, vanadium, and cobalt. Takefu calls them representative data for the grade’s standard values. The page does not present minimum and maximum limits or a certificate for a specific heat, blade, or scissor.
What is the hardness of VG10?
Takefu displays HRC 60 or above for its VG10 material. Jaguar separately states 59 HRC for its KAMIYU hair scissor. These source-specific statements do not create one universal HRC value or range for every VG-10-labelled scissor.
Does VG-10 guarantee long edge life or easy sharpening?
No universal finished-shear result is established here. Takefu makes material-level statements about wear resistance and sharpening for its VG10 blade steel, but it does not publish a salon edge-life test or service interval on that page. Check the exact scissor maker’s current use, care, and service information.
Are VG10 and VG10W the same grade?
No. Takefu publishes them on separate official product pages and describes VG10W as VG10 with added tungsten. Keep the two designations and their published data separate.
