There is in the collection one large double-edged knife (Fig. 112, No. 89298 [1162]) of precisely the same form as the slate hunting knife (Fig. 103) and Mr. Nelson’s jade knife previously mentioned. The blade is of thick sheet iron, which has in it a couple of rivet holes, and the haft of reindeer antler in two sections, held together by a large copper rivet at each end and a marline of sinew braid. Each edge has a narrow bevel on one face only, the two edges being beveled on opposite faces. There are a small number of such knives still in use, especially as hunting knives (for cutting up walrus, one man said). They are considered to be better than modern knives for keeping off evil spirits at night. As is not unusual, the antiquity of the object has probably invested it with a certain amount of superstitious regard. These knives are undoubtedly the same as the “double-edged knives (pan´-na)” mentioned by Dr. Simpson (op. cit., p. 266) as brought for sale by the Nunatañmiun, who obtained them from the Siberian natives, and which he believes to be carried as far as the strait of Fury and Hecla. It would be interesting to decide whether the stone hunting knives were an original idea of the Eskimo, or whether they were copies, in stone, of the first few iron knives obtained from Siberia; but more material is needed before the matter can be cleared up. The natives of Point Barrow, in ordinary conversation, call all knives savĭk, which also means _iron_, and is identically the same as the word used in Greenland for the same objects. If, then, there was a time, as these people say, when their ancestors were totally ignorant of the use of iron--and the large number of stone implements still found among them is strongly corroborative of this--the use of this name indicates that the first iron was obtained from the east, along with the soapstone lamps, instead of from Siberia. Had it first come from Siberia, as tobacco did, we should expect to find it, like the latter, called by a Russian or Siberian name.
