ESKIMO KNIVES often of pectolite, used as bone-breakers or whenever a maul was required, were crude affairs, consisting generally of natural, elliptical bowlders, or of pieces of convenient size, pecked into shape, and flattened at the end (pl. xtv). They were hafted in the same manner as the adzes. Kavives—Knives, for which no substi- tute equal to jade could be found in primi- tive times, were very different for the sexes among the Eskimo. The du, or wo- man’s knife (pl. xv), was quite uniform in shape, consisting of a thin, crescentic blade, ground down to a keen edge along the curved portion. Some were inserted in the groove of a handle of ivory, bone, or wood, which was often ornamentally carved; others were smoothed along the upper straight edge, which was generally expanded, and in some instances a groove on one or both sides was provided, seem- ingly for the purpose of giving the hand a better hold of the blade. This tool was] the constant companion of the woman, and was used for every possible purpose, from splitting fish to cutting a thread. AND MONOGRAPHS
