The razor looks great Korndog! cool filework design!

So...as for these super secret psa sanding discs...they are for rotary tools?
I have an Eliminator Geared Rotary Air Sander for automotive body/paint - 8" psa pad
I have Rotary & a RO Sanders for woodwork - 5" psa pads
All work great and I have always wanted a flat surface, interchangable adhesive sander bit for my rotary tools.

The snap on rotary tool sanding discs are good, but still have the metal ring in the center. I've thought about making my own, and stamping mini discs out of psa abrasives, but I could never think up an appropriate backing pad capable of withstanding rotary type rpm's and mounting to a rotary sized shank.

I would appreciate more info on these - or are they to remain secret. (or from the sound of it, are they something that is no longer available?)

how many fiber wheels, and bristle discs were sacraficed to this razor?
