Work Sharp Professional Precision Adjust Knife Sharpener Technical Specifications and RFQ Checklist
Byline: Vincent Xi, Editorial Author
> Buyer answer: Treat Work Sharp Professional Precision Adjust Knife Sharpener as a buyer search reference until a supplier provides configuration-specific evidence. This is a supplier-completion RFQ schedule, not a verified product datasheet. Compare quotations only when item identity, supplied contents, measurement methods, acceptance criteria, and commercial scope all refer to the same quoted revision.
The supplied source package contains no configuration-specific official datasheet, controlled drawing, seller-authorization record, warranty terms, packing specification, or sample test record for the named reference. It therefore does not verify a manufacturer, seller authorization, angle range, blade envelope, abrasive selection, material, dimensions, included contents, compatibility, origin, warranty, availability, or performance result.
RFQ Status Rules
| Status | Meaning in the RFQ | Buyer action |
|---|---|---|
| Confirmed | The supplier provides a record tied to the quoted identifier and configuration revision. | Attach the record to the quotation and approval file. |
| Exception | The supplier proposes a deviation, alternative, limitation, or unavailable requirement. | Record it separately for written buyer disposition. |
| Unknown | The supplier cannot support the requested field. | Do not convert the field into a purchase-order assumption. |
| Not applicable | The supplier explains why the field does not apply to the quoted configuration. | Confirm that the omission does not affect intended use. |
A marketplace title, product photo, generic catalog image, or unsupported statement is not sufficient evidence for a fit-critical specification, compatibility assertion, authorization claim, or acceptance result.
Quote Header and Identity Controls
Require these details before reviewing technical content:
- Buyer RFQ identifier, issue date, and revision.
- Named product reference used for the buyer search.
- Offer classification: branded product claim, authorized-channel offer, compatible or replacement component, unbranded comparable system, or private-label configuration.
- Exact quoted model, SKU, component identifier, and configuration revision.
- Seller legal entity and address.
- Manufacturer legal entity and production location, where documented.
- Authorization issuer, territory, document date, product scope, and warranty source when authorization is claimed.
- Compatibility basis and known interface limitations when a replacement or compatible part is offered.
- Tooling, artwork, marking, and change-control ownership for a private-label offer.
- Order quantity, destination, currency, price basis, delivery rule, payment terms, quote validity, and lead-time trigger.
- Supplier contact responsible for technical exceptions and document control.
For a branded or authorized-channel offer, request documentation tied to the exact quoted identifier. For a comparable or private-label offer, require a complete engineering response without presenting similarity as proof of authorization, interchangeability, or equivalent performance.
Technical Specification Schedule
Where the buyer has not set an acceptance value, use Supplier to propose and document rather than copying an unverified listing claim.
| RFQ field | Minimum supplier response | Required evidence |

Measurement and QC Evidence
Each record should identify the calendar date, sample or lot identity, configuration revision, unit, method, instrument identity, instrument status, raw result, calculation, acceptance limit, and disposition. A pass statement without those details is not enough for a fit-critical or performance-related field.
| Acceptance area | Required method definition | Required record |
|---|---|---|
| Identity and contents | Verify quoted identifier, revision, included components, markings, and packaging contents against the approved configuration list. | Configuration audit with pass, fail, and exception status. |
| Angle setup and result | Define blade geometry, clamp position, reference plane, carrier condition, selected setting, measurement location, instrument, and calculation. | Setup images, raw readings, and a dated instrument record. |
| Reset repeatability | Define reset action, reclamping condition, abrasive-change condition, reading sequence, and variation calculation. | Raw readings and a summary tied to sample identity. |
| Clamp retention and marking | Define blade profile, contact points, tightening procedure, test action, permitted movement, and surface-marking criterion. | Functional result and post-test visual record. |
| Abrasive and carrier fit | Identify the quoted carrier and abrasive; verify fit, orientation, retention, support condition, and replacement fit. | Fit record and controlled sample images. |
| Dimensions and interfaces | State nominal value, unit, tolerance, datum, instrument, and observed result for each critical interface. | Dimensional inspection report. |
| Assembly, finish, and packaging | Inspect lock operation, guide movement, interference, burrs, coating condition, contamination, transport protection, carton contents, and document inclusion. | Inspection checklist, packaging audit, and pre-shipment images. |
| Nonconformance | Describe the deviation, affected quantity, containment, proposed disposition, and buyer approval status. | Separate deviation or corrective-action record. |
For angle reporting, the supplier should state whether error is calculated as measured angle minus selected angle and whether the result is per side or inclusive. For repeatability reporting, state the variation calculation used. These reporting rules do not establish an acceptable limit for the named reference.
Buyer-Only Calculation Examples
The following values are buyer arithmetic examples, not named-product specifications, performance claims, or market data. Each is an assumption to verify in the supplier quotation and sample evidence.
| Example calculation assumption | Required context |
|---|---|
20 degrees inclusive / 2 blade sides = 10 degrees per blade side | Scope: hypothetical symmetric-edge planning example. As-of: buyer RFQ issue date. Source: buyer arithmetic. Status: assumption to verify in the supplier quote. |
30 degrees inclusive / 2 blade sides = 15 degrees per blade side | Scope: hypothetical symmetric-edge planning example. As-of: buyer RFQ issue date. Source: buyer arithmetic. Status: assumption to verify in the supplier quote. |
USD 1,200 total / 100 complete sets = USD 12.00 per complete set | Scope: hypothetical quote-normalization example. As-of: buyer RFQ issue date. Source: buyer arithmetic. Status: assumption to verify after all quoted inclusions and exclusions are documented. |
Do not transfer these examples into a supplier offer as verified capability, configuration, price, or acceptance criteria. Normalize quotations only after accounting for excluded abrasives, accessories, packaging, inspection, tooling, samples, freight, duty, taxes, and required spares.

Standards and Certification Handling
Name a standard only when it is relevant to a buyer specification, contract, tender, regulation, or destination-market requirement. The RFQ should then state the standard, edition, applicable scope, required clause or method, sampling rule, and evidence required.
A supplier inspection procedure is the supplier's own practice and is not proof of certification. Do not describe a product, seller, supplier, or facility as certified unless a current document identifies the holder, issuing body, validity, applicable site, product or process scope, and relevant revision. Confirm that the document covers the quoted configuration.
Source Context, Method, and Limits
Retained source contexts
| Retained supplied source | Permitted use in this package | Not used to establish |
|---|---|---|
| Leeknives sourcing guide | General supplier-screening context for identity and commercial-diligence questions. | Any specification, authorization, origin, construction, availability, or performance claim for the named reference. |
| BILIKNIFE production-process overview | General context for requesting supplier-controlled process and inspection records. | A claim that a quoted supplier uses a particular process or achieves a particular result. |

Methodology
This package separates buyer requirements, supplier declarations, sample evidence, and retained external context. The RFQ fields were derived from the information needed to compare product identity, configuration, interfaces, measurements, QC evidence, packaging, spares, and commercial scope without inferring named-product values from a title, photo, marketplace listing, or comparable-product description. The calculation examples are explicitly buyer arithmetic and require supplier confirmation.
Limitations and what to verify
The supplied source package does not establish a configuration-specific technical specification, controlled drawing, tolerance schedule, material declaration, authorized-distribution record, test report, warranty document, packing specification, spare-parts schedule, or certification document for the named reference.
Before purchase-order release, verify supplier identity and authorization where claimed; exact quoted configuration; physical sample; dimensional and functional results; abrasive replacement route; packaging specification; warranty issuer; origin documentation; change-control terms; exception register; and any standard or certification document required by the buyer contract.
