Abstract: Embodiments of the present disclosure generally relate to a pivoting assembly, to tools including the pivoting assembly, and to their methods of use in, e.g., collecting lunar samples. One embodiment comprises a shaft coupled to a handle at one end and coupled to a pivoting assembly at the opposite end. The pivoting assembly may comprise a slotted axle, a locking rod having a head engageable with a slot of the slotted axle, and a release handle coupled to the locking rod. The release handle is movable to move the head of the locking rod into a locked position and an unlocked position. A rotatable arm is coupled to the pivoting assembly and is rotatable relative to the handle when the head of the locking rod is in the unlocked position.
