A Welsh hook is a type of polearm, a halberd-like weapon with a hook on the back, and gained its name due to its prevalence among the Welsh soldiers during the medieval wars against the English.[1] It closely related to the agricultural implement known as a bill and is commonly classified as a type of poleaxe.[2]
Falstaff: "My own knee? ... and swore the devil his true liegeman upon the cross of a Welsh hook,—What, a plague, call you him?" (Shakespeare Henry IV Part 1, 290).[3]
