The processes denominated sharpening and setting a saw, consist, as the names imply, of two distinctoperations: the first being that of filing the teeth until their extremities are sharp; the second, that ofbending the teeth in an equal manner, and alternately to the right and left, so that when the eye is di-rected along the edge, the teeth of rectilinear saws may appear exactly in two lines, forming collec-tively an edge somewhat exceeding the thickness of the blade ^Xty^^^U /7i \h
