ABSTRACT:
A foldable spade includes an elongated handle with front and rear end portions opposite to each other in a longitudinal direction, and a biasing member which is disposed proximate to the front end portion, and a blade member with a blade surface wall. A front engaging member is connected to a proximate end of the blade member, and is journalled on the front end portion of the handle about a pivot transverse to the longitudinal direction so as to be rotated between a first position, where the blade surface wall extends forward from the front engaging member along the longitudinal direction, and a second position, where the blade surface wall extends rearward from the front engaging member to be folded over the handle. A rear engaging member is disposed on the front end portion rearwardly of the front engaging member, and is biased by the biasing member to move along the longitudinal direction to engage the front engaging member when the front engaging member is in the first position. The rear engaging member is movable against the biasing member to release the front engaging member to move toward the second position so as to superimpose the blade member upon the handle.
