Are you sure it is a pin? My 2 blade rages was a threaded allenwrench type. When I bought the replacement pack it had the pin system. If you have a allenwrench set for your bow it is the smallest one.
Nice to get one the old way I remember my first hunting bow when I started hunting was a bear recurve that cost me 35 dollars new. Now look what they cost best of luck and keep up the great tradition of stick bow hunting.
