Another form of knife or dagger has merely a flat tang, in some cases provided with rivets by which it could be fastened to a handle, in others without rivets, as if it had been simply driven into a handle. The blade shown in Fig. 251 was found in the same hoard as that engraved as Fig. 241. The rivets are fast attached to the blade, and the handle through which they passed was probably of some perishable material, such as wood, horn, or bone. Another blade (5¼ inches), with a broad tang and two rivet-holes, was found in the Thames.[743] In the British Museum is a knife much like the figure, 8 inches long, and showing three facets on the blade, found in the Thames at Kingston. The knife-blades with broad tangs, which were not riveted to their handles, were in some instances provided with a central ridge upon the tang, which served to steady them in their handles, and in others the stem or tang was left plain. One of the former class, from the Heathery Burn Cave, is shown in Fig. 252. It is in the collection of Canon Greenwell, F.R.S. An imperfect knife of the same kind, found in Yorkshire, is in the Scarborough Museum. Another, with the edges more ogival, like Fig. 241, was found in the neighbourhood of Nottingham,[744] with socketed celts and numerous other objects in bronze. Another, broader at the base and more like a dagger in character, was found with various other articles at Marden,[745] Kent. More leaf-shaped and sharply pointed blades of this kind, probably daggers rather than knives, have been often found in Ireland. One[746] (10½ inches) has been figured by Wilde. Another was in the Dowris hoard. In the Isle of Harty hoard, already more than once cited, was a knife with a plain tang, shown in Fig. 253. It has rather the appearance of having been made from the point of a broken sword, as the edges of the tang have been “upset” by hammering. The blade itself is now narrower than the tang, the result probably of much wear and use. The end of a broken sword in the Dowris hoard has been converted into a knife in a similar manner. In the collection of the late Lord Braybrooke is what appears to be part of a tanged knife, sharpened at the broken end so as to form a chisel. In the Reach Fen hoard was a knife (4⅛ inches) of much the same character, but not so broad in the tang. A flat blade with a tang for insertion in a haft must have been a very early form of metal tool. Among the Assyrian relics from Tel Sifr, in South Babylonia, such blades were found, of which there are examples in the British Museum. Canon Greenwell, F.R.S., has two leaf-shaped blades of copper, with tangs set in handles of bone rather longer than the blades, which were lately in use among the Esquimaux. In form they resemble Fig. 257. It will now be well to mention some of the other Irish specimens of this class.
