  The hook shape 2 includes a guide portion 21 extending from the tip of the hook shape 2 toward the back, and a blade portion 22 provided in the back of the guide portion 21 in the hook shape 2.

  The tip of the guide portion 21 that is the tip of the hook shape 2 is rounded. Therefore, when the upper sheet material is cut in a state where a plurality of sheet materials overlap each other, even if the leading end of the guide portion 21 contacts the lower sheet material, the lower sheet material is not damaged. Yes.

  In the blade part 22, the blade line 22a is separated from the cutting boundary 22b, and even if the upper sheet material starts to be cut at any position of the cutting line 22a, the cutting surfaces are gradually separated from each other until the cutting surfaces reach the cutting boundary 22b. It is supposed to be. Therefore, the cutting resistance of the upper sheet material can be suppressed.

  Further, the blade line 22 a of the blade portion 22 is curved according to the hook shape 2. By curving, the blade portion 22 strikes obliquely against the thick upper sheet material, so that cutting resistance can be suppressed.

  The guide portion 21 extends beyond the blade line 22a of the blade portion 22 in a direction in which the blade 1 for cutting the sheet material advances relative to the upper sheet material. The upper sheet material to be cut is guided by the guide portion 21 to the blade portion 22 while being lifted upward from the lower sheet.

  The hook shape 2 has a smooth curve from the end of the blade line 22a on the hook tip side to the back of the hook shape 2 via the guide portion 21.

  A screw for fixing the blade 1 for cutting the sheet material to the main body 4 of the cutter 10 for cutting the sheet material, which will be described later, passes through the long holes 3 and 3.

  The blade 1 for cutting a sheet material is manufactured by processing a stainless steel plate material. The thickness of the stainless steel plate is 1.0 mm to 2.0 mm. By manufacturing the blade 1 for cutting a sheet material with a stainless steel plate having a thickness within this range, the blade for cutting the sheet material is cut when the upper sheet material is cut in a state where a plurality of sheet materials overlap each other. Even if a portion other than the first blade line 22a contacts the lower sheet material, it is possible to prevent the lower sheet material from being damaged.

  Moreover, the cutting resistance of the upper sheet material can be suppressed by manufacturing the blade 1 for cutting the sheet material with the stainless steel plate within the thickness range.

  The hook shape 2 has a smooth curve from the end of the blade line 22a on the hook tip side to the back of the hook shape 2 via the guide portion 21. Also by this, even if parts other than the blade line 22a of the blade 1 for cutting a sheet material come into contact with the lower sheet material, it is possible to prevent the lower sheet material from being damaged.
