Soda Can Pen Holder

Step 2 Bending the rim

The reason for cutting at a level above the rim is this. After cutting the top off, simply twist the part above the rim to make a smoother edge. The aluminium is soft enough to be shaped with the fingers. Again if you are not careful, you can cut yourself. Use pliers if necessary. The reason why I suggest using fingers is that you want to keep the can smooth and rounded. Excessive force from any tool will bend and disfigure the smoothness of the can. Also, the aluminium can can(?) crack under excessive pressure.

If there are any deformities still present, use your judgement to press and squeeze (the can) to make it as round as possible.
