[The twisters]
(No. 89465 [962]) are flat four-sided rods of walrus ivory, respectively 4.4 and 4.7 inches long. At each end one broad face is raised into a low transverse ridge about 0.1 inch high and the other rounded off, with the ridge on opposite faces at the two ends. They are ornamented on all four faces with longitudinal incised lines, colored with red ocher.
The use of these tools, which was discovered by actual experiment after our return to this country[410] is for twisting the strands of the sinew backing after it has been put on the bow into the cables already described. The manner in which this tool is used is as follows: The end is inserted between the strands at the middle of the bow, so that the ridge or hook catches the lower strands, and the end is carried over through an arc of 180°, which gives the cable a half turn of twist. This brings the twister against the bow, so that the twisting can be carried no further in this direction, and if the tool were to be removed for a fresh start the strands would have to be held or fastened in some way, making the process a slow one. Instead, the tool is slid back between the strands till the other end comes where the first was, so that the hook at this end catches the strand, and the workman can give to the cable another half turn of twist. This is continued until the cable is sufficiently twisted, the tool sliding back and forth like the handle of a vise. The tools are used in pairs, one being inserted in each cable and manipulated with each hand, so as to give the same amount of twist to each cable. At the present day, these tools are seldom used for bow making, since the sinew-backed bow is so nearly obsolete, but are employed in playing a game of the nature of pitch-penny. (See below, under games and pastimes.)
These tools, of which we collected twenty-six specimens, are all of walrus ivory, and of almost exactly the same shape, varying a little in size and ornamentation. They vary in length from 3 to 5.7 inches, but are usually about 4½ inches long. The commonest width is 0.4 inches, the narrowest being 0.3 and the widest 0.7 broad, while the thickness is almost always 0.3, varying hardly 0.1 inch. Most of them are plain, but a few are ornamented with incised lines, and two are marked with “circles and dots” as in Fig. 286, one of a rather large pair (No. 56521 [249] from Utkiavwĭñ). These are 5.4 inches long, neatly made and quite clean. All the others show signs of age and use.
