Abstract: The invention relates to a spool for winding fine metal wire on, comprising a core and two flanges coupled to either end of said core, wherein the outer side of each of said flanges comprises multiple debossed areas that extend radial from said core and are evenly distributed around said core. The debossed areas reduce the spreading of the flanges when winding fine metal wire on.
