<P>PROBLEM TO BE SOLVED: To provide a blade for a cut hole formation which can solve a problem that design freedom is low, and a resistance power is difficult to be decreased, and to provide a stitcher with the blade. <P>SOLUTION: The blade that can form a cut hole P2 is used for a stitcher 1 in which a punching hole P1 and the cut hole P2 are formed in two or more papers P, a tip P51 part of a cut/raised piece P5 from the punching hole P1 is made to be inserted into the cut hole P2, the two or more papers P can be stitched together by the relation of the cut/raised piece P5 and the cut hole P2. The blade includes a window that receives the cut/raised piece P5 just before being inserted into the cut hole P2, and has a shape in which an edge for pressing the cut/raised piece P5 at the window and pulling it into the cut hole P2 is distributed to a region to a thickness direction larger than a thickness dimension of a blade material. <P>COPYRIGHT: (C)2013,JPO&INPIT |
