  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a chisel for cutting a chamfer, a fore-edge or the like of a building material board used for interior work of a building.

  Conventionally, various scissors are used as a tool which chamfers boards for building materials, such as a gypsum board used for interior work of a building, etc. Some of these scissors use commercially available cutter blades slimmingly because they do not require sharpening work and are inexpensive.

  Here, since the commercially available cutter blade is long, for example, it may not be appropriate to use it as it is for slimming a bowl. Therefore, when using a cutter blade as slimming, for example, it is devised to fold the cutter blade in two, use one cutter blade as slimming, and separately store the other cutter blade as a replaceable blade. .

  In this respect, the scissors of Patent Document 1 insert the cutter blade into the blade holding portion provided at the upper end of the pedestal and fix the cutter blade so that the cutter blade can be reliably folded at a desired position. ing. In addition, after cutting the cutter blade, the cutter blade remaining in the blade pressing portion can be stored as it is as a substitute blade for slimming.
