Beyond the pin of bone already mentioned, as having been found in one of the pits at Grime’s Graves, I am not aware of any bone or horn implements of precisely this character, having |41| been as yet discovered in Europe; but hammers of stag’s horn and detached tines have frequently been found in connection with worked flints, and may have served in their manufacture. I have, moreover, remarked among the worked flints discovered in this country, and especially in Yorkshire, a number of small tools, the ends of which present a blunted, worn, and rounded appearance, as if from attrition against a hard substance. These tools are usually from 2 to 4 inches long, and made from large thick flakes, with the cutting edges removed by chipping; but occasionally, they are carefully finished implements of a pointed oval or a subtriangular section, and sometimes slightly curved longitudinally. Of these, illustrations will be given at a subsequent page. They are usually well adapted for being held in the hand, and I cannot but think that we have in them some of the tools which were used in the preparation of flint arrow-heads and other small instruments. I have tried the experiment with a large flake of flint used as the arrow-flaker, both unmounted and mounted in a wooden handle, and have succeeded in producing with it very passable imitations of ancient arrow-heads, both leaf-shaped and barbed. The flake of flint on which I have operated has been placed against a stop on a flat piece of wood, and when necessary to raise the edge of the flake I have placed a small blocking piece, also of wood, underneath it, and then by pressure of the arrow-flaker upon the edge of the flake, have detached successive splinters until I have reduced it into form. If the tool consists of a rather square-ended flake, one corner may rest upon the table of wood, and the pressure be given by a rocking action, bringing the other corner down upon the flake. In cutting the notches in barbed arrow-heads, this was probably the plan adopted, as I was surprised to find how easily this seemingly difficult part of the process was effected. Serration of the edges may be produced by the same means.
