![]() The Wairau Bar adzes are some of the finest examples of knapping skill known anywhere in the world and suggest a high level of craft specialization. We also note the presence of ‘stitched’ edges on some adzes likely resulting from fine punch work. Examples of each of these adze types are illustrated. We describe four main manufacturing methods with functional elaborations, resulting in nine different adze types that are represented by at least 3 specimens each at Wairau Bar. references to documents), combined with valuations of those documents' quality. These documents are recursive lists of rated hyperlinks: each adze document (called a 'Manifest') is merely a list of links (i.e. Railroad adze - A carpenters adze which had its bit extended in an effort to limit the breaking of handles when shaping railroad ties (railway sleepers). Adze consists of special types of documents, accessible via HTTP, which contain recommendations. The weight of this adze makes it unsuitable for sustained overhead adzing. There is considerable agreement between Duff's system and ours, as different manufacturing methods create different cross-section shapes, and functional modifications are often related to the adze tang. Carpenters adze - A heavy adze, often with very steep curves, and a very heavy, blunt pole. We propose a new classification system that emphasizes technological and functional features of the adzes. Duff emphasized cross-section shape and the elaboration of the tang. Our results show different Duff types clustering separately to an extent, but there are issues of ambiguity in assigning types. ![]() We use Principal Components Analysis of morphometric variables to test the empirical basis of the Duff system - an analytical exercise that should have applicability to typological systems elsewhere. ![]() Here we describe the different types in the Duff system and analyse 148 adzes from the Wairau Bar site, which has a high diversity of complete adzes and is the assemblage that Duff used as the basis of his system. The adze typology devised by Roger Duff half a century ago is the standard across New Zealand and the rest of Polynesia. This simple definition seems to incorporate a variety of functional types, including what might be called adzes, chisels, and even axes and end scrapers in. Stone adzes are found throughout the Pacific islands and documenting their diversity is critical to understanding relationships between past human populations.
