Willie,

Sure - you can readily do it yourself with a common file (I would not even mess with grinding or machining and I have those capabilities at home).

IMHO, though, it would be a very awkward barely-better-than-nothing tool to use - too much mass relative to the screw, eccentric mount, big fat screwdriver.

Prol better off to epoxy a rare earth magnet inside the handle of the WAVE and stick a dimestore eyeglasses screwdriver in there.

HTH,

Tom
