Precision of cutPrecision of cut– Accurate cutting according to the markerAccurate cutting according to the marker
Clean edges:Clean edges:– Raw edges of fabric should not be frayedRaw edges of fabric should not be frayed
Un-fused edges:Un-fused edges:– Edges are fused due to the heat generated Edges are fused due to the heat generated
due to the friction of blade and fabricdue to the friction of blade and fabric
