The Gas Pedal® Brand  is THE original Thumb assist and still the best. 

Many others have copied us which is flattery. HOWEVER THEY JUST DONT GET IT RIGHT. Why? Because they dont understand the physics of balancing all four vectors of recoil force.

This is the one that started the opposable grip concept that has dominated every National and World Championship for last decade.
