Stone knives with wooden handles (fig. 55). These specimens include rude flakes 

 and finely-wrought blades. They are fastened with bitumen or gum, in short, 

 pointed handles, evidently for use as knives. They are of great importance to 

 the science of prehistoric anthropology as showing the methods of attachment 

 and use of flint flakes, blades, etc., in common use in prehistoric times. These 

 are found principally on the Pacific Coast, though some have been found in 

 Mexico and in Tennessee.

Slate knives are flat, thin, with a semilunar edge and with a straight back made 

 thicker and heavier, to be grasped in the hand (fig. 56). They chiefly occur- 

 along the coast and in the Northeastern States. Similar implements, likewise 

 made of slate with a curved edge and a-lateral tang, have been found in Penn 

 sylvania and in Indiana. Varieties of these implements have been used in his 

 toric times bvthe Indians of the northwest coast as fish knives.
