Masakari (jap. 鉞) in Japanese refers to a large axe (commonly referred to as an ono), such as those used to cut down trees or in the past as a battle axe or for punishment.
The blade of the masakari is made of steel. It is single-edged, the cutting edge is worked in the shape of a crescent. It is fixed on the handle with the help of a rectangular eye.
Opposite the blade a long, pointed spike is worked out, which is used to penetrate armor. As a weapon, the masakari was used by the Yamabushi monks as a battle axe in combat.
There are several versions, differing in length and appearance. This axe has been used very rarely in Japan.
