A monk's spade (Traditional Chinese: 月牙鏟; Simplified Chinese: 月牙铲; pinyin: yuèyáchǎn; literally "Crescent Moon 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. 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. 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.
