Ask anyone who's ever made buttons and it's likely they'll tell you that cutting the artwork for their buttons was the least enjoyable part of the experience. Most circle cutters are made of plastic. And because the AC-1 is made of high quality aircraft aluminum, it won't crack or break in the middle of a job, the way cheap plastic cutters can, and will.
Most cutters have a straight edge cutting blade that dulls quickly.
With the AC-1 you can cut more than one sheet of printed artwork at a time. Adjusting the AC-1 is done by means of a simple thumb screw. Just loosen the thumb screw, position the cutting arm where you want it, and then re-tighten the thumb screw. Notice that the AC-1 has a large plastic knob that will comfortably fit into the palm of your hand and allow you to easily exert the necessary downward pressure to make your cuts. The cutting guide insert, which comes with the AC-1 makes lining up the cuts for your button designs incredibly easy and accurate.
