BIGGER IS BETTER - COMMENTS ON KUHNS FORMAL APPROACH TO MOBILE TOOL KITS

Kuhn (1994) argues that small lithic tools provide an optimal means of reducing the weight of mobile tool kits while maximizing potential ut ility. This assertion contradicts much of the current thinking about m obility and the organization of lithic technology and is at odds with the archaeological record. A flaw in Kuhn's equation for calculating t he utility/mass ratio of retouched tools leads him to this erroneous c onclusion. Problems with Kuhn's utility/mass ratio equation are descri bed and an alternative formula is offered. The corrected formula indic ates that larger stone toots maximize utility at a longer transport co st. Experimental evidence for additional advantages of larger stone to ols is also provided.
