Abstract: A cutting device and method uses a power tool releasably engageable with a shank or drive shaft of a mechanical assembly powering a movable cutting blade. The cutting device can include a drive shaft drivably coupled to the cutting blade, a neck supporting the drive shaft, and a shank having a first portion fixed relative to the neck and a second portion drivably coupled to and rotatable with the drive shaft, wherein the drive shaft and/or the second portion of the shank is shaped and dimensioned for releasable engagement with the power tool. In some cases, one or more gears are drivably coupled between the drive shaft and the cutting blade, and are operable to transfer rotation from the drive shaft to the cutting blade.
