I tried using the "find" function here to no avail.

Spending the winter here in FL, can I legally carry my OTF knife here?

I can tell you that they are legal here in FL under our concealed weapons permit (as opposed to a license that only permits firearms).

I don't know for certain about the delineation of concealed versus open carry when it comes to a knife but I can't imagine it differs from a pistol.

Do you have a non resident Florida CCW or are you using your home state permit and reciprocity?

Home state CPL and reciprocity.

Can a non resident get one of these "concealed weapons permits" here in Florida, and if so how would I go about getting one?

Post your question in a new thread in the CCW forum, please.
