| Summary: | Composite tool hafting research has touched upon almost every era and region of human history. One aspect that has seen little attention is how those traces of hafting strategies might reflect the raw material of the endblade that an organic handle would have held. This aspect is particularly important for clarifying the scope and scale of novel raw material use in contexts that have concurrent use of different lithic, bone, and metal materials. This article analyzes harpoon heads from the Canadian Arctic in Dorset cultural contexts and identifies three different hafting techniques employed across time. For roughly one millennium, Dorset groups used a single harpoon endblade hafting technique. After AD 500, new hafting techniques were developed, corresponding with the emergence of metal use. Some of these methods are not compatible with common chipped stone materials and signal an increase in metal endblade production. However, surviving metal objects are underrepresented in museum collections because of various taphonomic processes. By recognizing the materials of the harpoon endblade and the specific constraints of some hafting techniques, it is possible to identify what these endblade materials may have been and expand the known extent and intensity of early metal use by observing the hafts alone. Les recherches sur l’emmanchement d’outils composites ont touché presque chaque ère et chaque région de l’histoire humaine. Un aspect qui a reçu peu d’attention a trait à la manière dont les traces des stratégies d’emmanchement pourraient refléter le matériau brut de la pointe qu’un emmanchement organique aurait permis de tenir. Cet aspect est particulièrement important quand vient le temps de préciser la portée et l’échelle de l’utilisation de nouveaux matériaux bruts dans des contextes où se trouve l’usage concurrent de différents matériaux de pierre, d’os et de métal. Cet article analyse les têtes de harpon de contextes culturels du Dorset dans l’Arctique canadien et fait état de trois techniques d’emmanchement ...
