After reading many reviews for the various brands of 1 inch circle punches I decided on this one for making bottle cap charms. There was one review in particular that stood out saying that the Martha Stewart punches are supposed to be among the best (if not THE best). That same reviewer said how that while there may be a few random bad MS punches, when you get MS they are usually good & the bad ones are usually rare.So I ordered the MS 1 inch circle punch, it arrived in true Amazon fashion (love Prime!), & was all set up to make bottle caps with my DD. Well, that lasted for about 2 seconds until the 1st test punch was made into a sheet of copy paper.... the smile quickly faded from our trusting faces after several more test punches & the realization that we must have received one of the rare MS punches with a burr or burrs on it.I wasn't about to disassemble it to try & file it down as one reviewer stated they had done, but I was bound & determined to try to put a smile back on my sweet DD's face who was trying to make Christmas presents for her sisters & friends. I closely examined & tried to feel the surface of the blade, etc. & I felt several rough spots / burrs that were causing the paper to get hung up in the punch, and would not allow it to cut completely through all around the entire circle. It also seemed like there might have been a section that was rubbing together with the outer circle that the inner punch was pushing the paper through.I first tried punching though aluminum foil, but that didn't work for anything (some reviewers said that would sharpen it). After that I didn't take the punch apart, but rather I squeezed it as though I was trying to punch through some paper & I lightly sanded the actual circle part that does the punch (one reviewer said they disassembled the punch & filed down the burrs, but I wasn't going to disassemble it & then not be able to return it) & also the edge of the metal where the circle punch pushes through (not sure how to describe it). Lightly sanding didn't help at first so I was a bit firmer. I noticed a slight improvement in the punch & the flap that wasn't entirely cut through was getting smaller so I used a medium grit sandpaper & sanded a bit more. VOILA! That did the trick... my DD was soooo happy as was I knowing she was happy & would have enough time for her projects to dry in time to wrap them to give for Christmas.We ran into an issue with some of the bottle caps not turning out as well as we wanted them to so we decided to remake some of them after looking at the them next morning once they were fully dry. The problem came into play then when I went to use the MS punch again the next day & it was not cutting right yet again.. mind you I only cut a total of 8 circles with it through photo paper & it wasn't working again. I lightly sanded the edges & was able to get 5 more cut out with jagged edges but the 6th one just wasn't happening.Later that day I contacted Amazon and the punch has been returned. I let them send me a replacement & made one punch with it through copy paper, which was fine, but I haven't yet used it on photo paper nor made a lot of punches with it, so I will update more when we do bottle cap charms rounds 3. I'm hoping this MS punch works great & stays that way. My advice is that if you get a bad one to start, don't try & fiddle with it.. either get a replacement sent (if from Amazon, etc. online) or go to a local store to get one you can test right away & return if it is a dud. Don't naively wait until you must have it to find out it won't work.Learn from my mistake, frustration, & disappointment!
