A Functional Analysis of Certain Chipped Stone Tools
Open accessAbstract
Abstract A Late Prehistoric period buffalo kill and butchering site in northern Wyoming (Site 48 JO 312) produced a large number of stone tools. Flakes removed in sharpening stone tools provided much of the interpretation of the activity that occurred at the site and in addition gave a number of ideas concerning tool use and sharpening.

TL;DR
Analysis of retouch ("sharpening") flakes from the Late Prehistoric Piney Creek bison kill and butchering site (48 JO 312) in northern Wyoming shows that five identifiable categories of flakes record stylized resharpening of bifaces, side scrapers, and end scrapers, and that these flakes often yield more information about site activities than the discarded tools themselves. Measurements of striking platforms allow estimates of how much tool width was lost per use-and-resharpening cycle and how many cycles a given tool underwent.
Key findings
- Five categories of retouch flakes were identified in the Piney Creek material: flakes of bifacial retouch; three categories of side-scraper retouch flakes (including flakes struck from the flat side of side scrapers, and subsequent conventional resharpening flakes); and end-scraper retouch flakes.
- By actual measurement, 100 flakes of bifacial retouch (all metamorphosed shales, the most common material at the site) had striking platforms of an average and median width of 2.2 mm; experiments suggested about 2.0 mm was the average width one biface edge was reduced per sharpening, with wear estimated at 1.0–2.0 mm, giving a total of 3.0–4.0 mm lost per edge per use-and-resharpening cycle.
- One biface (Fig. 2g) was estimated at about 75–80 mm wide when first broken and 46 mm wide when broken the last time and discarded; each blade edge was reduced between 14 and 17 mm, suggesting each edge may have been resharpened four or five times.
- At the site, "as much or more information, concerning activities performed there, was derived from the retouch flakes as from the tools"; in the kill area there was very little evidence of tool use in the form of actual tools, but retouch flakes demonstrated tool use commensurate with the operation.
Methods
- Excavation during the summers of 1964 and 1965 of a buffalo kill and butchering area along Piney Creek on the eastern flanks of the Big Horn Mountains, northern Wyoming; approximately 200 bison (*Bison bison*) were driven over a steep slope, with the kill area at the base and a butchering area about 300 ft. away. The operation is dated to around the latter part of the 16th century and represents a one-year operation, probably several drives within a drive season.
- Microscopic examination of unworked flakes, drawing on Bordes's (1961) concept of flakes of bifacial retouch, Semenov's (1964) ideas on use-wear traces, and Jelinek's (1965) notes on hard and soft hammer percussion; flakes were matched back into their flake scars on tools.
- Quantitative comparison of striking-platform widths of retouch flakes with experimental and observational estimates of edge reduction from wear and sharpening, applied to measurements of individual tools.
Limitations
- Stated by the paper: microscopic analysis is time consuming and the ability to recognize evidence of tool use is acquired with difficulty; straightforward interpretations may often be shown on only a small percentage of the total specimens; it is "as yet difficult to assign tool wear on a working edge to any specific function except within broad limits"; evidence is often difficult to photograph or otherwise preserve so that it can be seen and confirmed by others; and such analysis requires some background in the mechanics and use of simple tools.
- Stated by the paper: few end-scraper retouch flakes were recovered "due to the mesh size of the screens used in excavation," so that category is underrepresented in the sample.
- Evident from the text: the quantitative estimates of wear (1.0–2.0 mm) and of edge reduction per sharpening (about 2.0 mm) rest on experiments and comparisons rather than direct observation, and the paper itself notes the evidence comes from "a rather limited context," though it argues the results can be generalized.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-08, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-08 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
