The Hidden Edge Safety Knife

The ultimate in safety knives, Starrett SO11 Hidden Edge® keeps the blade safely tucked away when not in use, yet instantly available by simply releasing the safety lock and squeezing the lever to the knife body.

The cutting depth is easily and accurately adjusted with a thumbwheel.

With quick release blade change and storage for space blades in the lever, blade changes are fast and tool free - there is no need to take the knife apart to change the blade. An optional belt holster is also available.
