T.O.A.D stands for “Toggle Operated Anti-Drag”. We used a toggle mechanism similar to the one used later on with the E.T, except that it was all internal. This knife is extremely smooth because locking is done with pivot points vs. a locking arm that’s riding on the tang that falls into place. The pocket clip was reversible and adjustable for tension utilizing o rings as the spring mechanism. It is one of the few designs that never went into production with a company.
