Sleep Sword Zantoma

A sword resembling a distorted hatchet. Based on an ancient hunting weapon.
A machete-like weapon that makes full use of Hypnocatrice claws, feathers, beak, and more. Its design is adapted from a weapon used by an ancient hunting people, and the tip of the blade being shaped like a Hypnocatrice beak is a holdover from ancient times.
