The Leather Pocket Knife Case measures: 5 1/8 inches tall x 1.5 inches wide and deep. The difference in case sizes has only to do with the placement of the snap closure allowing a tighter fit – the case itself is the same size.
LARGE: The case will fit pocket knives up to 4 7/8 inches tall (when folded shut) x 1.25 inches wide 9/16 inches deep.
SMALL: For smaller pocket knives down to 3 5/8 inches tall (when folded shut) x 1.25 inches wide 9/16 inches deep.
Knife not included with case.
