With my arthritis, I never thought I could use a tool like this one! I am amazed at what the crop-o-dile can cut through! Oneach side of the handles they have a 1/8" hole cutter and a 3/8" hole cutter. They have even made it so you can adjust the depth of your hole punch for making all sides even. (I figured that out on a video on YouTube!) Then, setting the eyelets is quite easy, however, I really like the large eyelets versus the smaller simply because it is more comfortable with my fingers! I have used the crop-o-dile more recently to make holes in defective CD's so that I can make mini-scrapbooks out of them! Cutting through them was a snap. Some things are better done within the domain of a paper sack, so that the pieces don't fly out at you or your eyes, so just be careful! I also used it to add an extra two or three holes for my leather purse. Couldn't have been happier to cinch that bag up! I make the little Post It! note holders and use it to punch the small eyelets in them to put ribbon through. Beautiful, soft and gentle on my hands with very little exertion on my part. What a wonderful product. I forgot to mention that it is also very quiet!
