Scrapers (ikum) and Hide Softeners

Old Eskimo skin scraper with flaked chert blade (1-1/2” x 1-1/8” x 3/8”)
and curved “pistol-grip” wooden handle (2-5/8” x 1-1/2” x 1-1/2”) showing
two shallow finger hollows.
From Point Hope, Alaska.
Collected by F. A. Goodbrod (1894-1962), a mineralogist who prospected
throughout Alaska in the early 1950s acquiring artifacts from the native
inhabitants of Saint Lawrence Island, King Island, Point Hope, Kobuk River,
Yukon River, Galena, and Nenana.

Summary of Ethnographic Data
According to ethnographic data these scrapers were skin dressing tools necessary to the preparing of furs and skins used for clothing, boats, dog- harnesses, etc.
The handles were of ivory (extinct mammoth or walrus), bone or driftwood carved
to fit the hand of their user with indentations to receive the tips of the fingers and the thumb. The blades themselves were most commonly of
chert or some other material of appropriate hardness found during the warmer months along the stream beds. These stones were then properly modified and wedged into their handles with grass, bits of hide or cloth.
During the skin dressing process the skins were
scraped several times with the aid of this instrument. According to Murdoch (1892:294) women, who "appear to do most of the work," spread the skins out and thoroughly scraped them with this tool "which was grasped firmly in the right hand and pushed from the worker" to remove bits of flesh, fat, and water (Murdoch 1892:295). (Nelson [1901: 116] discusses a distinct division of labor concerning the dressing and tanning of hides.) With the smaller skins of hares, muskrats, and waterfowl,
this can be done on the thigh of the worker (Murdoch 1892:295); the skins of larger animals such as reindeer, bears, or walruses were probably placed flesh-side up on the ground, snow, or some other hard support (Witthoft 1958:98 and Semenov 1964:90-91), secured in some manner, and then scraped. The skins were then treated, most frequently with urine because of its sodium chloride and lime content (Semenov 1964:90), rolled into a
bundle with the hair side inward and kept in the house or kashim until they became sour and the hair loosened. The hair was then scraped off and the skin stretched on a wooden frame and placed
outside of the house to dry. When dry, the skin was softened by breaking the
grain, often with the use of a scraper and polishing stones. The eastern Eskimo
also used their teeth for this softening process. Only when the hide became a
soft, pliable leather was it ready to be worked. The use of skins was a very
important and necessary part of Eskimo life and their preparation involved a
tremendous amount of work.
Summary of Semenov and Wilmsenon
Functional Analysis
Wilmsen has suggested (1968:159) that different angle sizes on the working edges
of the tools are related to the different functions which the tools perform.
After obtaining measurements from nearly 1500 Paleo-Indian specimens and a
collection of 19 Eskimo scrapers, he observed that the edge angles of those
tools used mainly in the preparation of skins fell within a 46-55° range, while
those with steeper bits used for skin softening and heavy wood and bone working
were clustered between 66-75° (1968:156-157). It is interesting to note that 65
percent of all tool tips and concavities associated with tools in his sample had
edge angles in this latter steeper range (1966:157). For the Eskimo sample he
noted a mean value of 59° on the retouched distal end (1968:159).
It is not only the angle of the edge itself
that is indicative of the function which the tool served but also the shape of
the tool and its condition. The essential shape of all of these end-scrapers
used in the dressing of skins is semi-circular, allowing the actual edge of the
scraper to be as sharp as necessary to function without the danger of lacerating
the skins (Semenov 1964:88). The sharpness or bluntness of these blades, Semenov
believes (1964:87), is the only real distinction that can be made between
end-scrapers used for skin scraping and those used for skin softening.

Non-Hafted VS Hafted
Non-Hafted:
Commonly used in the hand.
These two groups have been divided into three categories: Side Scrapers,
which have one or both sides of an elongated flake beveled; End Scrapers,
which have the working edge on one or both ends of a long flake; and the small
thumb or Thumbnail Scrapers
which are shaped similar to a fingernail.
Hafted:
These were made from uniface blades; a
concave scraper edge was chipped into one side of the blade and a pair of
notches was worked into one end for hafting. On most examples, the base and
notches were ground. Occasionally they were made from broken projectile points.
Also, they may be part of combination tools, including extra scraper and knife
edges.
Sizes range 1 to 4
inches with the average being around 2 inches long.
