The edges of the arrow-heads made entirely with these flint arrow-flakers are, however, more obtuse and rounded than those of ancient specimens, so that probably these flint tools were used rather for removing slight irregularities in the form than for the main chipping out. This latter process, I find experimentally, can be best performed by means of a piece of stag’s horn, used much in the same way as practised by the Eskimos. By supporting the flake of flint which is to be converted into an arrow-head against a wooden stop, and pressing the horn against the edge of the |42| flake, the flint enters slightly into the body of the horn; then bringing the pressure to bear sideways, minute splinters can be detached, and the arrow-head formed by degrees in this manner without much risk of breaking. Not only can the leaf-shaped forms be produced, but the barbed arrow-heads, both with and without the central stem. The leaf-shaped arrow-heads are, however, the most easy to manufacture, and this simple form was probably that earliest in use. The counterfeit arrow-heads made by the notorious Flint Jack are of rude work, and were probably made with a light hammer of iron. Of late years (1895) a far more skilful workman at Mildenhall has produced imitations which can hardly be distinguished from genuine arrow-heads. He keeps his process of manufacture secret. Among many tribes[131] of America, arrow-making is said to have been a trade confined to a certain class, who possessed the traditional knowledge of the process of manufacture; and it can hardly be expected that a mere novice like myself should be able at once to attain the art. I may, therefore, freely confess that, though by the use of stag’s horn the ordinary surface-chipping characteristic of ancient implements may be obtained, yet the method of producing the even fluting, like ripple-marks, by detaching parallel splinters uniform in size, and extending almost across the surface of a lance- or arrow-head is at present a mystery to me; as is also the method by which the delicate ornamentation on the handles of Danish flint daggers was produced. It seems, however, possible that by pressing the flint to be operated upon on some close-fitting elastic body at the time of removing the minute flakes, the line of fracture may be carried along a considerable distance over the surface of the flint, before coming to an end by reason of the dislodged flake breaking off or terminating. It is also possible that the minute and elegant ornaments may have been produced by the use of a pointed tooth of some animal as a punch. Mr. F. C. J. Spurrell,[132] in an interesting article, has suggested that the final flaking was effected after the blades had been ground to a smooth surface, in the same manner as the flaking on some of the most symmetrical Egyptian blades. His view appears to be correct, at all events so far as certain parts of some Danish blades are concerned.
