Notes

Imported from the published Ahrex spec sheet for FW580 plus the Ahrex product page. Measured values (hook length, gap, wire diameter) are manufacturer-published and carried on the size rows as published_spec. Inferred, not published: bend_family round_kendal, eye_type and eye_orientation read from the sheet illustration. shank_length_category is set only where the model name states it, otherwise unknown - Ahrex does not publish an X-rating. Verify before relying on the inferred fields.
