Colmillo

is a technique used by Coyote Starrk while in his Resurrección, Los Lobos.

Description
Starrk rends off and materializes a portion of his own reishi, from either of the bandoliers along his arms, and solidifies it to construct a sword, which is durable enough to clash with Shunsui Kyōraku's Zanpakutō. While the blades formed by this technique vaguely resemble the katana he wields in his sealed form, they possess a curved, fang-like prong hanging from each corner of their guard. Starrk can manifest and wield two of these swords simultaneously.
