Review on 📐 Jielisi 12 Inch A4 Paper Cutter with Automatic Security Safeguard Guillotine - Ideal for Coupon, Craft Paper, Label, and Photo - Black by Summer Hendricks

This knife looks good, feels solid and the blade is sharp. I was able to cut 8 sheets of (thin) notebook paper; he fought for it. This cutter is almost exclusively in the metric system. Grid - squares-centimeters, ruler - centimeters on both sides. (Which you can't tell from the photos or description.) The only inches go down perpendicular to the ruler/blade - you can't measure inches anywhere else. If you want to crop the entire page/top of page, this works fine. If you need inch measurements along the cutting direction, e.g. B. for a partial cut of a certain length on one side, this cutter is not ideal for you. The accuracy is slightly lower. I tested the grid on two separate transparent rulers. If I align it at the top, they gradually shift down from the center, so the lines on this one "drift" a little precisely, but I'd guess it's <1%, so it's probably good enough for many uses in the size range that this cutter is capable of. Because you don't have a perfectly flat surface (part of the ruler is lower than the rest because it has to be tucked under the base), it's difficult to measure more than 4 inches. This seems to be most accurate when the side follows the base curve down rather than straightening, so you have to be careful about the trade-off between accuracy and side curve. The angles are even less precise, but still almost unusable. If you try to cut at an angle, the paper will interfere with the ruler closing, so you'll either have to crush and fold the paper, or make a smaller section. If you want to cut out a 45 degree isosceles triangle, the largest triangle you can make is 2 inches on the sides before you hit the ruler. (If you want to avoid using a comb to line the paper, you can't.) For example, you can't cut a 5-inch origami square in half—at least not without using the angle of the lines as the cutting guide. Another reviewer complains that there is no guidance as to where the blade is. It is still possible to align these. The ruler doesn't block your ability to see the groove for the blade, if you line up the paper at each end of it then you can position the paper exactly where you want it, or you can mark the bottom of the page with a Measure with a ruler (including the drawer, see above). Spare blade on this one. I would recommend removing the second blade to have more room and a better view for alignment. I couldn't completely cut the side using the guides along the same side as the second blade. because the second blade was close enough that you can't get the last fragment of the page. Removal instructions on packaging, but basically you place the blade in the center, bend the ruler, and slide the blade through the extended center of the clear ruler. Then you have to figure out where to place it so that it doesn't damage the blade or damage something else. plastic container. This means that even if you run your finger along the underside of the blade block, you probably won't cut yourself (unless you're really trying to be stupid). I was planning on storing this stand on a shelf but the blade/guide tends to open up when I stand it on a flat edge so it takes up more room than I was hoping. The lack of imperial units is not ideal; it is a US customer base. Part of me wants to send this back because the description didn't make it clear and there will be times when I want the Imperial to be along the cut direction or for my grid. The mathematically exact part of me doesn't like unit drift. Another part of me thinks it's probably "good enough" for many uses, and there are workarounds for missing imperial units. I'm considering sending it back.
