Vintage 1920–40 Case Tested XX Green Bone Jack Knife – Pattern 6214 – Early Era Collectible

This vintage Case Tested XX jack knife (pattern 6214) was crafted between 1920 and 1940, during Case’s legendary “Tested” era. Featuring classic green jigged bone handles with nickel silver bolsters, this compact jack knife embodies the rugged utility and timeless style that made Case an American cutlery icon. Both blades remain tight with good function. The clip point has a slightly soft opening snap, while the pen blade has the faintest bit of side-to-side play, though this does not affect usability.

At over 80 years old, this knife has matured into a true collector’s piece—a workingman’s knife that has survived in honest condition with excellent character.
