Replace relative size names with version-specific measurements, weight, and documented use information.
Begin with the versions that actually exist
Mini, standard, and large are relative names, not measurements. First identify the currently offered versions and their exact SKU or model codes. Do not assume that every named size is available, that standard is a universal baseline, or that the labels follow the same scale across different product families.
Create one column per verified version. Preserve the full name and code at the top so measurements cannot drift between variants. If a page combines several options, recheck the displayed code and specifications after each selection.
Replace labels with comparable fields
Use the same units and measurement definitions for every version. Record overall length, closed or stored length where relevant, the dimensions of the functional portion, usable gripping length, maximum width or thickness when documented, and total weight. Add mechanism, included accessories, and stated intended use as separate fields rather than treating them as consequences of size.
The gripping area deserves its own row because overall size does not reveal how much usable hand space a design provides. Weight should also remain independent: a longer version is not necessarily heavier in a predictable proportion. If two sources measure from different reference points, keep the values separate until their methods can be reconciled.
Do not assume proportional scaling
A size label does not prove that every dimension changed by one fixed percentage. Nor does it show that the mechanism, blade geometry, accessories, or intended task stayed the same. The SEWARD Terms of Service advises checking dimensions, function, compatibility, selected options, and model-specific information on the individual product page. Accordingly, each version needs its own confirmed data.
The finished comparison should support conditional conclusions, such as which documented version is shorter or lighter. It should not convert the words mini, standard, or large into an unsupported claim about comfort, performance, or suitability.
