4-SPLIT TOOL Perforating Tool -- from Pergamano
Helpful tool for cutting perforations along outlines and contour lines. Insert this 4-needle tool into the paper at a slight angle -- the connection breaks immediately so you no longer need to cut it. The results are beautiful. It should be noted, however, that this tool does not produce the refinement of a cut edge. (Dot illustration enlarged.)

Tool was designed due to popularity of 2-Needle Split Tool.
From Pergamano®, The Netherlands.
