A new stapler-type fiber cutting tool for obtaining good fiber end surfaces is described. T he size of the tool is about 2 cm wide, 3 cm high, and 10 cm long. The weight is only 90 g. In principle, the fiber is scored and than fractured by applying the tensile stress and bending stress simultaneously. The optimum conditions for cutting the fiber are investigated: The blade pressure is from 15 to 32 g, tensile stress from 6 to 13 kg/mm2, and bending stress around 10 kg/mm2. The average breaking angle of 0.6is easily obtained. It is confirmed that the tool is fully endurable for use in field.
