Appletons' cyclopaedia of applied mechanics: a dictionary of mechanical engineering and the mechanical arts . unt-edged knife, curved to suit the inclined rest of the beam-house,and used to scrape hides. A keen-edged knife is used in the beam-house to remove short hairs (newgrowth) from the hides. Fig. 2773 represents the curriers knife, which is double-edged, rec-tangular, about 12 in. in length and 5 in. in width, with a straight handle at one end and a cross-handle at the other, the axes of both being in the plane of the blade. The latter is a plate of steelcarefully and peculiarly tempered, and is ground to a straight edge by rubbing it forward and back- LEATHER-WORKING TOOLS—CURRYING. 287 ward on the rub-stone, which is a block of sandstone placed on a strong trestle of convenient upper surface should be a perfect plane. Hub-stones of Nova Scotia sandstone are cylindrical,about 8 in. in diameter by 1 ft. in length. The scratches left on the blade by the rub-stone are re-moved by rubbing on a fine Scotch or Welsh clearing-stone, which leaves a wire edge. The work- 2768. man then takes a turning-steel, and by rubbing it carefully from end to end turns the edge complete-ly over. To keep the knife in this condition requires the greatest skill, as it cannot be used formore than a minute without losing its keenness. To restore this, the point of a small steel (finger-steel) is first run along the groove formed by turning the edge over, and then the steel is made topass along outside the edge. When used, the plane of the knife-blade is held almost perpendicularlyto the skin. In the operation called skiving, the skin is laid over the beam, and the rough fleshy portion isshaved off by the currier drivinghis knife obliquely a few inches at a time, keeping the right-handhandle slightly in advance of the left-hand one in the downward motion. In shaving, the knife isdriven from the top to the bottom of the beam, thus taking off slice after slice, removin
