Leather-Splitting Machine, Fig. 2767.—This apparatus is used for splitting hides, the skin beingcarried by the rollers against a long fixed blade. It may be operated by hand-power. LEATHER-WORKIN< 1 TOOLS—CURRYING. The various hand-tools used by curriers are illus-trated in Figs. 276S to 2773. Figs. 276S and 2769 are fleshing knifes, and are used to scrape off thehide and to remove adherent flesh, lime, and dirt. Fig. 2769 is a German flesher. The hide, whilebeing fleshed, is placed on the convex surface of an inclined beam, which consists, first, of a heavyblock of wood upon which the currier stands. Into one end of this block is mortised a stiff block ofwood, faced with light wood and then with a plate of mahogany or lignum vitae. The inclination ofthe beam, Fig. 2770, depends on the convenience of the operator, who holds the leather by pre
