I am embarking on a new project which is combining my fascination
with pietra dure for wood and scaling it down to jewelry size.
I saw this at the Tucson Gem Show at GJX and was blown away.
After talking with a good friend of mine who does pietra dure in
wood and learned the process in Italy said I needed this particular
saw to do the work.
From Gryphon Corp:
There is no practical way of forming an .008" wire into a
continuous loop for rock cutting purposes. A knot cannot be
used and a weld of no extra diameter is too weak to provide
proper tension. Moreover, a continuous loop will not permit
internal cuts to be made in a design. The Gryphon Micro Wire
Saw therefore uses a long length of wire which repeatedly
reverses direction as it comes to each end. In order for the
wire to remain in a constant position on the cutting platform,
it is held on a threaded drum which in turn rotates on a screw
of the same pitch. One turn~s looped up over a wire pulley
which is counter–weighted to provide tension. As much as 50
feet of wire (and as little as 3 feet) may be held on the drum.
The height of the loop is adjustable so that perfect
squareness can be maintained.

They don’t make this unit any more, but they do maintain it, if I
find one that is in need of repair. If any of you know where I could
get one, please let me know. I am watching Ebay of course, but if
there is another source for this item I’m all ears.
