The STP FrogA(R) pattern was created to provide a cutter to meet the needs of trout, bass and other panfish fly tyers. The STP FrogA(R) fly design provides the tyer with an accurate, multi-colored body and legs with realistic movement and durability. The STP FrogA(R) fly lands upright on every cast with proper attitude in the water and is easy to tie, but with enough artistry of construction so as to be pleasing to the fly tyer, regardless of skill level. Brandon Z and Rudy C show that variety is the STP Frog. What variations will you come up with for the STP Frog Foam Body Cutter? But will it catch fish? Intensive testing has proved that the STP FrogA(R) fly will catch fish as Richard Pilatzke shows with a grey colored STP Frog fly. Individual cutters available in sizes small (10), medium (6) and large (2). Each individual cutter comes with a small cutting pad. STP Frog Foam Body Cutter Sets contain each of the three sizes of cutter, a matching tool caddy and larg cutting pad.
