A monk's spade (Traditional Chinese: 月牙鏟; Simplified Chinese: 月牙铲; pinyin: yuèyáchǎn; literally "Moon Tooth Spade"; also, Traditional Chinese: 禪仗; Simplified Chinese: 禅仗; pinyin: chánzhàng; literally, "Zen Weapon". Romanized Japanese: getsugasan, Hiragana: げつがさん), also called a Shaolin Spade, is a Chinesepole weapon consisting of a long pole with a flat spade-like blade on one end and a smaller crescent shaped blade on the other. Neither blade were designed to be sharpened. In old China, Buddhist monks often carried spades (shovels) with them when travelling. This served two purposes: if they came upon a corpse on the road, they could properly bury it with Buddhist rites, and the large implement could serve as a weapon for defence against bandits. The crescent was designed as defense against small to medium sized predators such as wild dogs and jaguars. The way it is used is to hold the animal at bay by positioning the crescent at the animal's neck and pushing it away if needed. Over time, they were stylised into the monk's spade weapon.
The character Sha Gojyo in the Japanese manga and anime series Saiyuki wields a modified form of this weapon with great skill and dexterity.
The monk's spade (under the name "Shaolin spade") was listed in Max Brooks' Zombie Survival Guide as a highly effective hand-to-hand anti-zombie weapon, as it can decapitate a rotting corpse with ease and its length allows users to engage opponents both from a distance and with both sides of the spade.
