A shank is a type of knife, often characterized by its simple, sharp blade and a handle that allows for easy grip. Typically made from metal, the blade can vary in length and shape, but it is usually designed for cutting or stabbing. Shanks are often associated with improvised weapons, particularly in prison settings, where they may be crafted from everyday items. In addition to their use as weapons, shanks can also refer to tools used in various trades, such as butchering or crafting. The term can also apply to the part of a knife that connects the blade to the handle, which is crucial for balance and control during use.
