I bought this to cut some stiff, 5mm-thick self-stick felt pads. I saw this would cut 30 sheets of paper, which measures about 5mm, so I ordered this with fingers crossed.When it got here, I lined up a pad and lowered the blade. It cut through the pad like butter---square and straight---exactly what I was hoping for.The only drawback for me is that the metric measurements don't run all the way top to bottom, so you're stuck with the half-inch marks, which isn't great if you're measuring in millimeters.The measuring marks only go down to 1.5 inches, so if you need to cut something thinner than that, you're out of luck. Lastly, you really do need to use the clamp properly, because otherwise what you're cutting can shift and ruin the cut.Beyond those minor quibbles it's great. It's very heavy with rubber feet so it stays put. The cutter blade locks down after each cut for safety, and then releases easily for the next cut with a pull on the conveniently-positioned trigger release. It does a great job and feels like it will last a lifetime.The Stakcut Paper Trimmer exceeded my expectations! I would purchase again. It is so sharp you have to be very careful when using.Pour découpage de feuilles a l'aide d'une tranche très efficace et fiable. Je suis très satisfait de la qualité du produit. L'emballage était impeccable, ayant totalement prétégé le produit obtenu. Merci.
