Designed during The Henian Period (7th to 11th Centuries), the Bisento was in The Pole Arm family of weapons. Comparable to the European Glaive – the weapons featured a long, sword-like head. Ranging in length from 2.5 to 3 feet, the Spear head was broad (4 to 6-inches) and single-edged. This cutting and slashing blade was mounted on a 10 to 12 foot wooden pole. The sheer size was intimidating enough. Not a throwing weapon, they were very effective against charging enemy cavalry, or whole Regiments could break up a charge (or counter-charge). Due to the sheer length of The Bisento, they were not used by cavalry.
