Abstract
Abstract A belt buckle knife is disclosed in which a knife portion can be removed with the knife blade locked in its open position without the need of removing the belt buckle knife from the belt. The belt buckle knife includes a buckle portion which engages and fastens the belt independent of the knife portion. The knife portion is selectively operable from a knife closed position to a knife open position. In the knife closed position, the knife blade is engaged by an open tapered groove running along the length of the buckle portion, with the knife portion and the buckle portion being securely fastened together. In the knife open position, the knife blade is locked open with respect to the knife handle, and the knife portion can readily be removed from the buckle portion.
