The Trouble with Ham Steaks: A Reply to Morrow

Toby Morrow argues that I (Kuhn 1994) made an error in calculating the utility/mass ratio of retouched tools, and he proposes an “alternative” formula. Unfortunately, Morrow confounds utility per se with ratio of utility to weight, and, as a result, his alternative approach is erroneous. This response to Morrow examines the central issue of how artifact utility is assessed. The main message of my original paper is reaffirmed. Utility/mass ratios eventually begin to decline as artifacts get large, and optimal size ranges can be estimated based on a few simplifying assumptions.
