A machete is a broad blade used either as an agricultural implement similar to an axe, or in combat like a long-bladed knife. The blade is typically 30 to 66 centimetres long and usually under 3 millimetres thick. In the Spanish language, the word is possibly a diminutive form of the word macho, which was used to refer to sledgehammers. Alternatively, its origin may be machaera, the name given by the Greeks and Romans to the falcata. It is the origin of the English language equivalent term matchet, though this is rarely used. In much of the English-speaking Caribbean, such as Jamaica, Barbados, Guyana, Grenada, and Trinidad and Tobago, the term cutlass is used for these agricultural tools.
