I have a short story to tell you ... I ordered this product, and at the time I thought I would love it, now I have a memory problem so when I got it, I wondered ... what in the sam hill was I thinking ... so I opened it up and put it in a holder and promptly forgot all about it.
Then one day, one of my frames I had made out of cardstock hadn't cut clean ... I didn't want to cut it with scissors, unfortunately, I am a perfectionist and I knew that it would look different than the other edges ... all of a sudden I remembered this file set. Fortunately for me, my craft room is all labeled (remember the memory thing) ... I pulled them out and looked at each piece and carefully used one of them on the rough edge. Now, I have to admit it looked much better but not quite right, so back to the precision files once again, and I pulled out another one that looked like it might do the job ... and with careful filing... I finished the edge to perfection.
Since then where I don't use it constantly, when I NEED IT THERE IS NOTHING ELSE THAT WOULD DO THE JOB AS WELL AS THIS DOES! I am sooooo glad I bought it ... it is wonderful!!!! Give it a try where you may not need it all the time, but when you do ... you will wonder how you ever got by without it!
