B3 21" Heavy Duty Paper Trimmer, Safety Lock, Metal Base, 10-Sheet | Guillotine-style precision cut, Effortless Operation, safety lock guard, solid metal base, clean 10-sheet capacity

This commercial-grade paper trimmer features a 21" maximum cutting length and is perfectly suited for B3, A3, B4, A4, B5, A5, B6, and B7 paper sizes. It can cut up to 10 sheets of 20lb printing paper at once, fully accommodating different cutting needs for size and capacity. Equipped with upper and lower dual steel bars, the upper bar has a curved design for increased friction during cutting, ensuring straighter, burr-free, and more consistent cuts. The base has laser-printed inch and metric dual scales that never fade, with a magnetic paper guide to precisely align paper for professional 90° cutting every time. Constructed with heavy-duty, high-quality steel, this paper cutter includes a plastic paper clamp to secure paper firmly and prevent shifting, while keeping your fingers away from the blade during use. When not in use, the blade locks securely into the bottom cylindrical latch to prevent accidental opening, movement, or potential injury. Unlike fragile plastic base paper trimmers, the solid steel base is designed for high-intensity and high-frequency use. It will not deform or crack, keeping the surface perfectly flat and stable even for bulk cutting in busy offices, workshops, or printing houses, ensuring durable and reliable performance. This manual, battery-free paper cutter handles various materials including copy paper, photos, cardstock, labels, business cards, and thin craft metal sheets up to 0.3mm/0.01in. It is the ideal tool for scrapbooking, paper DIY, offices, schools, homes, printing shops, and photo studios
