In People v. Henderson (1999) 76 Cal.App.4th 453, the court stated: "In . . . People v. Simons (1996) 42 Cal.App.4th 1100, the court was asked to decide whether a screwdriver could be a deadly weapon under Penal Code section 417.8. The Simons court . . . recited the long-standing distinction between weapons that are inherently deadly or dangerous and those that are deadly or dangerous based only on the facts of the particular case: '"'There are, first, those instrumentalities which are weapons in the strict sense of the word, and, second, those instrumentalities which are not weapons in the strict sense of the word, but which may be used as such. the instrumentalities falling in the first class, such as guns, dirks and blackjacks, which are weapons in the strict sense of the word and are "dangerous or deadly" to others in the ordinary use for which they are designed, may be said as a matter of law to be "dangerous or deadly weapons." This is true as the ordinary use for which they are designed establishes their character as such. the instrumentalities falling into the second class, such as ordinary razors, pocket-knives, hatpins, canes, hammers, hatchets and other sharp or heavy objects, which are not weapons in the strict sense of the word and are not "dangerous or deadly" to others in the ordinary use for which they are designed, may not be said as a matter of law to be "dangerous or deadly weapons." When it appears, however, that an instrumentality other than one falling within the first class is capable of being used in a "dangerous or deadly" manner, and it may be fairly inferred from the evidence that its possessor intended on a particular occasion to use it as a weapon should the circumstances require, we believe that its character as a "dangerous or deadly weapon" may be thus established, at least for the purposes of that occasion.""
