PROBLEM TO BE SOLVED: To efficiently form even a plurality of pairs of differently cut pieces in excellent and uniform shapes from an original block in a solid rectangle shape without requiring an experienced technique nor taking time and labor. SOLUTION: A device for obtaining the plurality of differently cut pieces includes: a first blade pattern 10 for obtaining diagonal cut lines, which are cut from one side of each small block e<SB>1</SB>, e<SB>2</SB>, e<SB>1</SB>', e<SB>2</SB>' to the other side, to face mutually oppositely from both the respective planes of the original block E to the half of the thickness by block unit by the use of respective thin blades 10a, 10b, 10a', 10b'; a second blade pattern 20 for obtaining straight cut lines, with a width being the same as that of the diagonal cut lines over the whole width direction length of the block unit, from the center of a thickness place in the original block E by the use of respective thin blades 21-24; and a straight cutting blade 30 for dividing the original block E with the respective cut lines by block unit.
