Description: Trimmer features a unique dual-rail system that stabilizes the rotary blade, eliminating wiggle for straight, perfectly precise cuts. As a bonus, it cuts a wide range of thick materials. The spring-action rotary bypass blade stays sharp and never needs to be replaced. Additional innovations include a built-in smudge guard and top quality work surface for long-lasting performance. Grid line measurements on the top and bottom allow you to use the base to your left or right. Convenient folding design takes up less space during storage and transport.
