This is a video showing how the corners look on top of each other, and how well it works for Project Life crafting. I also show the bottom so you can see how easy it is to open it up and throw away the excess corners. I had recently returned Martha Stewart's corner cutter, because it wouldn't make any clean cuts. This corner cutter with 3 different sizes has exceed my expectations.

Finally! The right sizes & it works consistently!

How difficult can it be to find a decent corner rounder, right?! Apparently, it is REALLY difficult, cuz I tried at least 8 or 9 at various sizes & hated them all! - including the big huge heavy duty chompers from WeRMemory Keepers. They are either (1) not quite straight, leaving the rounded corner lopsided (2) they require you to turn the darn thing upside down to see what you are doing in order to line up the punch, then the paper still slips when you actually execute the punch, (3) they are so tight that it takes all my considerable weight to punch a corner, knocking it askew & resulting in a crooked corner, (4) they break after a too few punches, (5) they are super heavy to heft and store, (6) they stop dialing sizes properly, etc. etc. etc. THEN, this one finally shows up as a #1 seller. It is GREAT! First of all, the corners are the sizes I need - the small is about the same radius as you'd see on laminated IDs (I've since gone on a rampage, cleaning out my entire family's wallet & laminating everything & rounding corners on everything), the medium is the perfect size for rounding corners on photos or card envelopes (I think the one on the envelope punch boards are a bit too large to allow you to make a pretty liner or punch a cute little design in the corner) - see the pix I uploaded for an example, the large is perfect for rounding card corners without eating up too much of the design. I wanted to get through my holiday cards before leaving a review, so that I can indicate what it works on consistently. It works well on paper, cardstock (I tried 65# to 140# watercolor paper), foil cardstock, foam, glitter stock, 40# vellum, and even some card corners that have stenciled texture paste. I didn't like how it worked on felt, since the cuts weren't as clean.

Worth every penny!

This corner rounder is awesome! It works every time, contains all the little pieces trimmed off, and has 3 size options for how rounded you want the corners to be. Also if you have small pieces that won't reach in the punch just use a sticky note to help it reach! :)

Don't take my word for it - take a look at the evidence and judge for yourself.

Used this handy tool to cut 1000 corners into heavy cardstock this morning. It's efficient - the job took me about 45 minutes - and the cutter never broke a sweat. Consistent cut quality. If I had a quarter-star deduction to take from this review, it's that I couldn't cut a larger corner with it. That's the only thing it's missing. You can't go wrong with this - the photo speaks for itself.

Very nice

Just corner rounded 1000 cards (4000 corners) of 130 lb cover. Every corner came out perfect. I was looking for a 1/4 inch corner rounder. This unit is in metric but the middle of the three sizes was basically 1/4 inch. Certainly on this heavy cover stock this was a one-at-a-time operation. You'd probably want to stick with one-at-a-time even for lighter paper. I was a little worried that it would break because another reviewer had a bad experience. Theirs was either defective or they may have tried stock that was too heavy. 130 lb cover is very heavy stock though, and 4000 cuts is a lot of work. The unit showed absolutely no signs of wear and tear after this job. Normally I'm not very impressed with these little plastic consumer-grade tools. In this case someone did a phenomenal job designing this little gem.

Corner rounder perfection

I can't tell you how much I've spent on stupid corner rounders, trying to find just one that creates a good, consistently round corner for my projects. There's nothing worse than cutting that corner only to find that your rounder suddenly decided your card would look better with only a half-round corner. So frustrating!! Finally, I've found the rounder to change my life. It feels flimsy when you first pick it up, but it's not. Mine has not let me down so far, at least. You get three corner size options, and while the back isn't open to "see" what you're doing, there are lines on either side of the rounder so you can guide your paper in properly. I've used it probably 100 times already and never once have a had a corner that didn't live up to expectations. This puts the Fiskars, Martha Stewarts, and the EK Successes of the world to shame. Look no further- you've found your rounder!!

I like that the cutter contains all the little scraps after ...

For my use of this corner cutter I primarily cut the corners of laminated sheets for my projects for my toddler. Cutting the corners allows her to be able to safely handle these papers/photos without cutting herself. I like that the cutter contains all the little scraps after cutting in the bottom that you can easily take a part of clean. Sometimes when using the medium setting it can be difficult to know i I am getting it under the blade because of the design at that junction. All in all I am very pleased with the product and foresee it lasting for quite some time. I will note that about 9 out of 10 times it misses and leaves a little nick on the corner. I just then have to peel away that portion and it looks fine. I would suggest that users use this product on a sturdy surface like a desk. Because it is so lightweight, in the beginning I would just use it in my hand but I felt that it cut better when it was sitting on a hard surface instead. Picture Note: Purple cards show before and after. You can also see how the cutter collects the scraps in the bottom of the device.

Hands down this thing is fabulous

Let me just say this thing is fabulous. I use it to crop the corners on my artist trading cards as well as other little bits of paper and its so nice having all three options in one cutter. It cuts smooth and saves the bits so you don't end up with a mess all over your floor. I highly recommend this - those rounded corners just give my cards a much more polished finished look to them.

Honestly the best corner cutter I’ve ever used

I do paper crafts on a regular basis including cardmaking, scrapbooking, and making bookmarks which are the three main reasons that I use a corner cutter. I own several corner cutters that each serve a purpose, or so I tell myself, but this one is the most versatile and best at cutting through thick materials such as laminating folders or cardstock. The best thing about this corner cutter is the grip. To cut the corners off, you press down on the decent-sized lever instead of trying to fit your thumb onto a itty-bitty little button like so many corner cutters. I was actually able to cut about twenty corners in a row comfortably without any hand discomfort. With many of the smaller and cheaper cutters that I have used in the past I have only been able to cut a few corners in a row before my hand began to cramp. Overall, I would highly recommend this corner cutter for anyone looking. It’s absolutely fabulous. It makes cutting through thicker items a breeze and it’s comfortable to use with minimal effort. No more hand cramping or having to use my palm to push down on a corner cutter that doesn’t want to cut.

Wonderful product

I can't say how this compares to other corner rounders since this is the first I've ever owned, but this is a lovely one that certainly does the job! I just rounded the corners on 300gsm watercolor paper around 150 sheets and that was a little bit of a struggle (that's the thickest I would recommend anybody cuts) and I definitely had to apply more pressure (as expected). I also cut corners on 150gsm sketch paper and that worked perfectly as well. The brown chipboard in the picture was NOT cut by the corner puncher, only the paper! All 3 settings are equally easy to use, and other reviews about how to make it easier to punch (holding down label?) are accurate. Great for the price!
