There are also a small number of peculiar forms, each represented by a single example. These vary in the length and breadth of the flanges and the shape of the blade. When a sufficient number of these shall have been recovered, it may be advisable to expand the present classification to include them. Many of the implements included in the adze class are admirable for their symmetry and perfection. A specimen secured in the Lake Superior region has a portion of the wooden handle still fitted in the socket. [Illustration: FIG. 593. (S. 2–3.) Copper chisel and awls.

Collection of the Logan Museum, Beloit, Wisconsin. ] _Spatulas_ Of the copper implements known as spatulas only a small number of examples have as yet been recovered in Wisconsin. The blade of these artifacts is usually broad and thin and irregularly rounded or somewhat triangular in outline. The handle is short, seldom more than three eighths of an inch in thickness, and nearly square or somewhat rectangular in section. Specimens are to be seen in the State Historical Museum, Milwaukee Public Museum, and other local collections. They range from four to nearly six inches in length. [Illustration: FIG. 595.

Left to right: Hartford, Washington County, Wisconsin; Merton, Waukesha County, Wisconsin; Wayne, Washington County, Wisconsin. ] The Reverend W. H. Beauchamp has described and figured both an iron and a copper implement of this class from New York. The possible employment of these implements in the shaping of aboriginal earthenware, the removing of the flesh from skins and bones, and of the scales from fish, has been suggested. They are but poorly adapted for use as spoons. The small number of specimens on hand at present makes it undesirable to venture an opinion of their utility. _Knives_. (_Figs. 597, 598._) In point of numbers these easily rank second to the numerous class of socketed spear-points. They have been recovered in considerable numbers in many parts of the state. At least four distinct types and some intermediate and peculiar forms are recognized. The close resemblance of some of these to the white man’s knife has frequently been remarked upon.
