Most cutters cut downward, which means the blade can nick whatever sits beneath the material. OLFA's Maru Cutter 29B takes a different approach: the circular blade scoops under the sheet and rolls through it, so the cutting edge never presses against the floor, tabletop, or cargo below.

The 45mm tungsten steel disc is the key to its longevity. Because the blade is round, it has far more usable cutting edge than a snap-off blade. When one section dulls, loosening the butterfly nut on the back of the body lets you rotate the disc to a sharp section without any tools. Full replacement follows the same simple process: loosen the nut, remove the screw, fit a new blade.

The round grip is sized to sit comfortably in either hand, and the design works for rope, PP strapping bands, paper, carpet, bubble wrap, and general sheeting. It is a tool built around one specific motion done well.
