The Executioner

The Almace (unofficial) is future hunter Cardin Winchester's weapon of choice.

Design
Almace is a large, black mace, with the flanges being extended farther outward than a regular mace would with a decorative gem in the middle. Cardin is capable of weilding it in one hand, suggesting either Cardin's excellent strength or its possible lightness.

Jaunedice
Cardin weilds Almace against Jaune Arc during a dual against each other at the beginning of the episode. After effortlessly disarming him of his shield, he blocks his opponent's attack with the shaft and knees Jaune, downing him.
