Looking for Pleskunas "Power Rasp"

I am looking for one of the old Pleskunas "Power Rasp" sanding blocks.  After 15 years, mine has lost most of it's abrasive and I would love to find another one, that would see me thru the next 15 years.  If anyone has a good used one, or preferably a NOS one, willing to pay full price.  Send me an email at: surfpro@hawaii.rr.com or text or call direct at: (808) 479-8235   Mahalo and Aloha, Randy Rarick    Sunset Beach, North Shore, Hawaii
