(15.) The complete mould, comprising “side” dies such as B, and “face” dies such as A, substantially as described, or illustrated in the drawings. (16.) The complete apparatus substantially as described, or illustrated in Figs. 1, 2, and 3, and Figs. 4, 5, and 6 of the drawings. (17.) The described method of pointing or sharpening rock-drilling and similar tools. (18.) The described method of forging and pointing or sharpening rock-drilling and similar tools.
