I have all three sizes. I also have the Creative Memory hex punch in two sizes. I cut card stock with the punches with no problem. I use different color card stock for each size which helps me keep them organized. My grand loves to punch for me too. I had so many I bundled them in packages of 100 and sold them at our guild sale table. The punches won't last for ever and won't cut two layers at a time and will not cut fabric.
