Hard Wires Only Cut of top : φ 0.6 〜 1.0mm Cut of side : φ 1.0 〜 1.2mm ● Flat Cut End——The flat cut edge diminishes the adjusting process. It is enough to polish the edge slightly. It prevents a wire from making shorter than expected. ● Compact & Powerful——Good manupilation even for whose hands are small. ● Safety Design——Safe because the blades are untouchable by fingers.
