Cleaver (tool) in the context of "Archaeological industry"

A cleaver is a large knife that varies in its shape but usually resembles a rectangular-bladed tomahawk. It is largely used as a kitchen or butcher knife and is mostly intended for splitting up large pieces of soft bones and slashing through thick pieces of meat. The knife's broad side can also be used for crushing in food preparation (such as garlic) and can also be used to scoop up chopped items.

Tools described as cleavers have been in use since the Acheulean period. "Cleaver" was commonly spelled clever in the late 17th century.

In the archaeology of the Stone Age, an industry or technocomplex is a typological classification of stone tools.

An industry consists of a number of lithic assemblages, typically including a range of different types of tools, that are grouped together on the basis of shared technological or morphological characteristics. For example, the Acheulean industry includes hand-axes, cleavers, scrapers and other tools with different forms, but which were all manufactured by the symmetrical reduction of a bifacial core producing large flakes. Industries are usually named after a type site where these characteristics were first observed (e.g. the Mousterian industry is named after the site of Le Moustier). By contrast, Neolithic axeheads from the Langdale axe industry were recognised as a type well before the centre at Great Langdale was identified by finds of debitage and other remains of the production, and confirmed by petrography (geological analysis). The stone was quarried and rough axe heads were produced there, to be more finely worked and polished elsewhere.
