The new Kizer Sparrow designed by Vincent Rizzo is a smooth folding knife with multiple openers (flipper, thumb hole) and a textured green micarta handle. The black stonewashed blade and parts offer a classy contrast to the ergonomic handle. The curved handle and the chamfered edges make it  not only fit the palm of the hand but also facilitates the opening and closing of the knife. The position and size of the thumb hole have been tested repeatedly to make the operation more convenient.
