After all layers have been glued on, the cone is cut. In this step it is decided whether the cone will fly well or badly. Only when the cone has been cut off exactly can it develop its full potential. To do this, the wrapping aid is pressed firmly onto the cutter's workbench. Then it is guided to the blade of the cutter knife and pressed. Then the winding aid is rotated past the blade. After several turns you will notice how the upper part of the cone detaches from the winding aid. The cone is almost done.
