A two-tone blade page should map each visible region to a product-specific image and assign a treatment name only where formal documentation supports it.
Define the regions before naming them
A clear two-tone presentation begins with an annotated image of the exact product version. Use simple region identifiers, such as Region A and Region B, and point each label to a precise boundary. Multiple views may be necessary where the transition wraps around an edge or is hidden by the viewing angle. The image should distinguish blade regions from reflections, shadows, grind geometry, markings, or adjacent components.
Keep positional descriptions neutral and repeatable. Terms such as upper visible area, lower bevel area, or spine-side region are more useful than decorative names when the formal product terminology is unknown.
Give each region its own evidence line
For every labeled region, record visible color and documented treatment separately. A practical entry can contain the region identifier, visible color, formal treatment name, and the product-specific source supporting that name. This prevents one verified treatment from being applied automatically to the entire blade.
If documentation confirms only a color contrast, publish only that contrast. Do not infer that a dark region is coated, that a bright region is polished, or that either area has added wear or corrosion performance. A visible boundary establishes an appearance boundary, not necessarily a process or performance boundary.
Resolve ambiguity at the version level
Confirm that the annotated image, selected option, and written specification all refer to the same version. The SEWARD Terms of Service advises checking exact product details and notes that photographs assist comparison while screen settings can affect colors and finishes. If the image and specification cannot be matched confidently, mark the affected region’s treatment as unconfirmed. This preserves an accurate two-tone description without inventing a divided finishing process.
