PRESTO FLYING JACK Pullball Bone switchblade knife by William Schrade

PRESTO FLYING JACK Pullball Bone switchblade knife by William Schrade, great grandson of George Schrade. This knife was inspired by one of George Schrade's patents that never went into production and his Great grandson made it a reality. These are hand made by William Schrade and fairly limited production. The knife measures 4 inches closed including the pull disc and 7 1/8" open with steel liners and nickel silver bolsters. The clip blade is etched PRESTO with wings and is 100% full with all of the original finish. The jigged bone scales are very attractive and in perfect condition. The knife works great with the tip deep in the well closed (held by the release mechanism), opens nicely and stays open as it should, though it does not lock open by nature and just held open by pressure from the backspring like most manual folding knives. New condition in original box.
