The rougher kinds are usually clumsy in their proportions, as if strength were an object, and they not unfrequently show a certain amount of abrasion at each end. An instrument of this coarser description is shown in Fig. 347. It is worn away and rounded, not only at the point, but for a considerable distance along the sides, the abraded surface having a somewhat bruised appearance. It is remarkable that many of the Danish flint knife-daggers, especially those which have been so long in use that their blades have been much diminished in size by having been frequently re-chipped, present at the
