How to load the wire with grit/ source of abrasive grit?

Abrasive? With tungsten wire, why not EDM? Tungsten is
refractory, but not noted for abrasive embedding capability.
Soft iron, or brass, is a more typical wire-saw candidate.
Rockhounds often use coathanger wire...


Skimming Dremmel and parting disc over a sheet of fine grade silicon carbide
wet & dry, in a paper cup, gives a source of fine grit . Now how to sputter
spot weld to wire, whether fine W, Cu , Al or ni-cr that I have around.
