    This is a well-designed, well-made tool.  It can be adjusted to work for you.
    5 Stars
    This is a well-designed, well-made tool. It can be adjusted to work for you.
    (I mean, unless you’re trying to round off a steel latch plate or something. Get an angle grinder.)Things to know:-There are multiple moving parts-These parts are probably not in perfect adjustment right out of the box.-You can make the adjustments necessary to do your project, using a Phillips screwdriver.I sympathize with those who had frustrations right out of the box with this item. For me, the blade assembly got stuck in the down position while chomping index cards (one at a time). But I fixed it, and the following description may help somebody out there.First, it’s worth bearing in mind that this product is made in Japan (not elsewhere in Asia), so you should expect the design and manufacturing to be very good. And it’s not a solid-state electronic device so you should expect to be able to disassemble and service it to some degree.Aside: If you just want nice-looking stationery without having to adjust, maintain, or even understand your tool, then give your project to the kid at the copy center. But if you are like me and enjoy that kind of thing, or if you just really want to cut corners, then it’s best not to, um…cut corners.Moving Parts: This product cuts a radiused corner in sheet material (usually paper or card stock) as the lever pushes the curved blade down across the edge of a metal plate, rounded with a matching curve, that support the material horizontally.The user operates the cutter via a lever that pivots on one side and presses down on the blade housing in the center (For you kids at home, that’s called a Class 2 lever, like a wheelbarrow). Maybe there is a video out there with a hand model who makes it look easy to use one finger on the tip of the lever, or squeeze it between your thumb and finger, but don’t bother. Use a solid work surface (wooden table, tile floor, concrete driveway, deck of a ship, whatever is convenient) and push straight down on the center, using your palm. This should give you the best chance of a clean cut the first time. The thicker the material, the more you must put your weight into it.Another Aside: The horizontal metal thing that opposes the vertical blade during the cut, is what I’m calling the “shearing plate”, because that is what we’re adjusting. The real technical term is probably in Japanese, so you’re welcome. I like to be accurate enough so you know what I’m talking about, but I promise not to get ridiculous about it and string a bunch of terms together for the sake of precision like they would do in German (“Ent now, ze tenshun iss adjustet bei tyrning ze Shearingplateassemblybasehousingsecurefasteningscrew…”)The shearing plate, fastened to a small movable plastic block, is meant to slide outward a bit with each cut. When the lever resets, the shearing plate assembly returns toward the center via a spring. You can’t see these springs without disassembling the product, but you can adjust the resistance to the spring tension via one of three screws underneath (one for each radius size).If the screw is totally snug and the shearing plate assembly does not move at all, the blade housing is likely to get stuck in the down position. If the screw is too loose, there will be enough play that the shearing plate assembly to move too soon or cant too much, resulting in either a ragged cut or no cut at all. A loose shearing plate will also fail to reset flush with the base, which narrows the cutting slot enough that it may not accept another sheet after the first cut.The correct adjustment will vary according to the material. For light thin cutting, like one sheet of printer paper, the screws should be “almost” snug. Wear eye protection at all times. To avoid stripping the threads in the plastic base, turn the screw by holding the screwdriver by the SHANK (not the handle) between your thumb and fingers, and turn clockwise until your finger grip fails and you would have to change to gripping the handle to turn any further. That is snug (or “finger tight”). Then back off by about ¼ to ½ turn. For thicker cuts, back the screw off a little more. Test and see. Again, if it’s too loose, the cut will fail in thick material, and a second sheet may bind on the way in. I got this to work for several sheets of paper, up to six stacked index cards, and two layers of a plastic drawer liner. Do some tests first to get the adjustment right, then push as hard as necessary. If your full body weight pressed over a stiff arm is not sufficient to round the corner off your material, then either it is too thick for this product to cut effectively, or you are severely malnourished. Break for a sandwich and try again later, or try the angle grinder.

    I create a lot of things using my laminator. When cut, there are a lot of sharp edges. I used to trim them by hand.

    This little gadget works great! Perfect, rounded corners every time! I use the medium setting.

    Totally recommend this little item!

    5.0 out of 5 stars Perfect rounded corners
    Reviewed in the United States on February 23, 2024
    I’ve been making little divination decks for myself, playing with words and watercolors and this makes them so much more elegant and refined. Its easy to use and I appreciate having three size options. I used the large punch for the larger squares and the small punch for the little squares.

    I’m using thick (watercolor) paper so I’m only punching one at a time but I’m fine with that, since I’m not trying to do thousands of them. I read a ton of reviews and this seemed to be the best option. I’m glad I went with it - I’m super happy with my purchase!
