The Dahle A4 Personal Rotary Trimmer (3rd Generation) with a 320mm cut length is lightweight and portable for just about any application. It features a self-sharpening blade, an automatic clamp to prevent shifting, and a metal base for durability. This highly accurate cutter is German engineered and ideal for trimming paper, photographs, and cardstock.

This trimmer features a self-sharpening cutting system. No need to worry about replacing dull or worn blades, this system sharpens as you cut to maintain a perfectly honed edge. The blade's precision graduated edge will remove even the tiniest sliver of paper and produce a clean, burr-free cut.

Holding your work securely by hand is no longer necessary. The trimmer's integrated, automatic clamping system provides even pressure that prevents your work from shifting.

For measuring, the base contains carefully screened guides to help align your cuts. The guides indicate inch and metric measurements for all your trimming needs. Dahle's 507 can trim up to 7 sheets of paper at a time and offers a 12" cut length. It combines all the precision you need, with the convenience of portability. It's a popular choice among photographers, craft enthusiasts, and office professionals.
