A plurality of cutting teeth are disposed at intervals in a complete circle around the periphery of a flexible cutting element. A frame is coupled to the cutting element to receive and guide the cutting element. Means is coupled to the cutting element and to the frame to impart an oscillatory motion to the cutting element to enable the oscillating teeth of the cutting element to cut a selected material. A simplified version of the present invention includes first and second handles coupled to opposite ends of the flexible cutting element to enable an operator to impart an oscillatory motion to the cutting element.
