Problems solved by technology

[0002] Now in the manual cutting operation, it is often necessary to use a ruler to cut against or fold the paper flat, and use a paper cutter to cut the paper according to the crease, and the ordinary paper cutter must use other tools to accurately cut the paper. Polygons, and the paper cutter itself does not have the function of measuring special angles. If you need to cut regular polygons and special angles such as 30° and 45°, you need to use multiple tools to achieve it.
