All birdseye maple handles will vary in color and striation, which is part of the uniqueness of natural handle materials.
From Spyderco: The immensely popular Chaparral series celebrates a diverse range of handle materials by incorporating them into the same, sleek gentleman's folder format. This stunning expression of the Chaparral showcases genuine birdseye maple scales and the dramatic grain pattern characteristic of this material. All other features are consistent with the Chaparral platform, including a full-flat-ground CTS® XHP® stainless steel blade, stainless steel liners, a sturdy back lock mechanism, and a reversible deep-pocket wire clip.
