There are 21 serrated scrapers. These are usually serrated on one edge
only, but other sides often show secondary usage. The serrations appear
to have been made in the course of the primary flaking, by blows dealt
at intervals, with the remaining protrusions left instead of being
chipped off. Some with steep sides would have been useful as scrapers,
but several small thin specimens could have been used as saws. Flinty
materials were preferred. The largest is 2 × 1¼, the smallest 1 × ¾
inches. From the ethnographic data (see below) it is interesting to
note that the Ute used serrated scrapers for taking the hair off hides.
“Uncompahgre” Scrapers (Fig. 36)
Six complete and one broken artifact are included in this category.
They conform in general to Wormington and Lister’s (1956) description
of those found at the type locality. Those at LoDaisKa are smaller.
Specifically they are flakes, usually triangular, although one is
rectangular. One edge is flaked on one face alone, one or more edges
are flaked on both faces. The butt, generally the striking platform
of the flake, is usually unflaked and thick. They appear to have been
serviceable without hafting, and are probably a multiple purpose tool,
possibly with a specific combination of uses. The largest is 2 × 1¾
inches; the smallest, 1¼ × ⅞ inches. All but one are quartzite.
