    Say your files and or other tools have for example gold dust on them
    and that gets imbedded in the surface of the platinum. Then you need
    to do a solder or weld joint on the platinum then the gold will burn
    into the surface of the platinum leaving a poor pitted surface. It
    is like the problems of having a little lead on the surface of a gold
    or silver piece and then soldering on it. This is the only reason I
    know of for the separation of tooling.
