The pattern-welded structure of this blade, though definitely present, is difficult to depict in a photograph, as the corrosion pattern allows only small foci of pattern to be discernable and never are all three bands clearly visible side by side. Examination of the full length of the blade discloses three bands of alternating twist forming a herringbone pattern. In this view the chevron pattern points toward the hilt (the left). The overlay on the right emphasizes the herringbone pattern (orange) with a thin weld boundary (yellow) between two bands.
