Maryland Case Law: - "'Gravity knife' constituted a dangerous or deadly weapon." (1964) - "Pocketknife with the blade already open did not require any time to open the knife, as one would with a penknife, contained all the offensive qualities of a switchblade or gravity knife because it was instantly available for violent use, and was not a penknife within the statutory exception." (1990) - "On the face of the statute, there is no indication contradicting the view that a penknife is a penknife whether small or large, whether the blade is closed or open, whether the blade is locked open or unlocked, and whether it is carried concealed or openly." (1991) - "A folding knife without switchblade but with a locking device... falls within the exception for 'penknives without switchblade" in this section." (1986) - " A buck [sic] knife (a knife having a blade which folds into the handle and which locks into place when open) carried with the blade open was 'penknife without switchblade' within statutory exception, and this status was not altered by knife's blade-locking device or fact that it was carried with its blade open." (1991) - "Where defendant's conviction was on the basis that the utility knife was a dangerous and deadly weapon per se, but the Court did not consider defendant's intent, the Court of Appeals reversed the conviction and remanded for a new trial." (1992) - "Location of the defendant, including whether he or she is in a public place or on private property, is simply one factor for the trier of fact to consider..." (1995) - "For objects not legislatively classified as dangerous and deadly per se, the State must prove that the object is within the class described as any other dangerous or deadly weapon of any kind." (1992) - "Where the only evidence presented was that the object appellant was carrying was a knife over three inches long, this evidence was insufficient to meet the statutory requirements of this section." (1992)
