Some of the things that I use my corner rounder for are identification cards, laminated items such as menus or other items that people will be handling (rounding the corners eliminates the sharp corner edges) and recently, on the inserts of wedding invitations that I was making. I rounded the corners on the invitations as well as the R.S.V.P. cards.

In my arsenal of tools of the trade, I have three different corner rounders. The first one pictured is actually the first one I bought many years ago. It is small, measuring less than two inches square and approximately one inch high, and cuts a 1/4 inch corner. Placed on your desktop you insert the corner of the paper or card stock, and press down on the white button on top. The one I have is old and as with most of my tools of the trade, I worked it beyond its capacity and it has done a great job! Manufactured by Carl, you can find it on the Internet for under $10.

The second corner rounder I have is a Fiskars. This one also has been tested to its limits by me and has worked very well. I like the squeeze handles and being able to keep it in my hand as my other hand moves the paper corners into the rounder. One thing I do not like about this one is that when you insert the paper corner there is a tiny little metal piece in the rounder that the corner of the paper has to be exactly in line with in order to get a nice rounded corner. If the corner of the paper isn’t lined up exactly, the little metal piece will bit a corner out of the paper corner. Once this happens, it can’t be fixed without trimming the paper making a new corner to then cut. Sometimes it feels like the paper is in right but it’s not. There is a little window that you can see to make sure the corner of the paper is in the right place before squeezing the handles. This corner rounder also makes a 1/4 inch cut and can also be found on the Internet for $10 and under.

The third is a Lassco CR-20 heavy duty corner rounder I purchased for an order that required rounding corners on laminated badges. What I like about this machine is that I can do multiple items, even laminated ones, at the same time. This one came with a 1/8 corner die but additional dies (1/4, 1/2 and 5/8 inch) can be purchased and easily changed on the rounder. To use this machine with multiple items, first be sure that they are lined up smoothly so when you insert them to cut, you will get a nice smooth cut all the way through. This rounder comes with a right-angled piece of wood that can be used to help hold the items in place that are being cut. To keep the cutter from jamming, the bits of paper that get cut off fall into the box below. There is a door on the side that opens to for emptying. The surface space is approximately four by eight inches. There is another model available that has a drop side that can be raised giving a larger surface to work on.

Lassco makes many corner rounding machines from this one to ones that are industrial grade. The Lassco CR-20 can also be purchased on the Internet for under $200, but if you do a little searching you can find it for less.
