Egyptian flint knives, for the knowledge of which we are mainly indebted to Prof. Flinders Petrie, and the workmanship of which is absolutely unrivalled. They are of two kinds, both presenting an outline curved on one or both sides. For the one kind a flake from 8 to 9 inches long of triangular section with a thick back and sharp edge has been taken; the back has been most carefully retouched and left slightly convex; the ridge of the flake has been wrought so as to show a crinkled line like that on the handles of some Danish daggers, the edge has been more or less re-worked, producing a bold convex sweep, and what was originally the inner face of the flake has first been delicately fluted by cross-flaking and then still more finely retouched along both the back and the edge.
For the other kind the whole surface of the original flake has, as Mr. Spurrell[1] has pointed out, been carefully ground, one face being made rather more convex that the other. The flatter face has been left almost untouched, but one side has been trimmed by flaking at the edge into almost a straight or slightly concave line; the other side is boldly curved, the general outline having been produced during the grinding process. The more convex face has been fluted or "ripple-marked" by cross-flaking from either side in the most skilful manner, the whole of the original polished surface being sometimes removed. The projections at the butt-end between the successive flakes have next been levelled down by secondary chipping, and finally the curved edge has been minutely serrated, there being about 36 teeth to the inch. These blades are from 7 to 914 inches in length, and occasionally made of beautiful chalcedonic flint. They are attributed by Professor Flinders Petrie[2] to a period between the fourth and the twelfth Dynasty, but may possibly be of even earlier date. As already mentioned, some beautiful leaf-shaped lance-heads with finely-serrated edges have been made in the same manner.
One of the fluted knives in the Ghizeh Museum[3] is hafted for a distance of about 4 inches in a thin plate of gold, engraved on the one face with well-drawn figures of animals, and on the other with floral ornaments arranged between two serpents. The plates of gold are not soldered together, but sewn one to the other with gold wire.
