This is an 80 mold knock off mainly used for Freestyle but was also used for
Ultimate and Whizbo. It was first in production in the early 80s, probably around
1980 or 81. It
has a grippy band going around the top of the disc in place of rings. The rings
were still under a patent by Wham-O. Each of these listed here is a special custom
disc produced in limited quantities. We only have one of each available. All are
in excellent condition with minor storage wear. Produced for California State
Frisbee Championships at Sonoma State University.
