A knife assembly capable of cutting photographic strip material with high accuracy at extremely high speeds includes a base, a stationary blade, a source of rotary power, a crank shaft, a spring-wrap clutch mechanism, first and second linear drive shafts, first and second adjustable linear bearings, and a movable blade. The spring-wrap clutch is mounted on the crank shaft for selectively imparting rotary power to the crank shaft, and the first and second linear drive shafts are connected to the drive shaft. The movable blade is connected between the ends of the first and second linear drive shafts.
