What evidence is sufficient to support a conviction for possession of a concealed concealed dirk or dagger?

Appellant contends the evidence was not sufficient to support a conviction for possession of a concealed dirk or dagger in that at the time of the knife's discovery it was closed and, therefore, not capable of ready use as required by Penal Code section 12020, subdivision (c)(24). We disagree. Under this section a folding knife that is prohibited by Penal Code section 653k "is capable of ready use as a stabbing weapon that may inflict great bodily injury" without it being exposed and locked into position. (See People v. Plumlee (2008) 166 Cal.App.4th 935, 940-941.)
