A spear is a pole weapon consisting of a shaft, usually of wood, with a pointed head. The head may be simply the sharpened end of the shaft itself, as is the case with fire hardened spears, or it may be made of a more durable material fastened to the shaft, such as flint,obsidian, iron, steel or bronze. The most common design for hunting or combat spears since ancient times has incorporated a metal spearhead shaped like a triangle, lozenge, or leaf. The heads of fishing spears usually feature barbs or serrated edges.
中國標準的槍形的武器總共有「矛」、「鈹」、「槊」等稱呼。「矛」和「鈹」這兩種稱呼比較早出現分別是在商代與東周。應邵《風俗通義》矛長八尺曰矟,《唐六典》卷16引此文作「丈八尺曰矟」,故知槊在東漢之前即有丈八槊矛是也。《說文解字》槍,歫也。漢簡《蒼頡篇》按,歫人之械也。槍,謂木兩頭銳者也。東漢.服虔《通俗文》剡木傷盜曰槍。故知槍在秦代即有。隋唐之後此類武器多稱為槍。中國槍從武術上使用的1~2公尺的槍到長槍陣用的8公尺長的長槍都有。
