I've had this knife for awhile now with out my dad knowing(my mom knew) and when he saw it he flipped and said it was most likely illegal. The blade is less than 4inches and when its folded(closed)with the covering around it it's about 4inches. I know that some kinds of knifes are illegal but I'm not sure about mine.
It seems dangerous to rely on this. L.B. v State 700 So.2d 370 (1997) suggests that a closed folder of 3.75" is okay, due in part to an identical AG opinion from 1951 (stating knives up to 4" are common pocketknives). However, that "common pocketknife" exception is only for the definition of "weapon". "Concealed weapon" in 790.001 has no "common pocketknife" exception as the "weapon" statute does; this distinction is presented in Baldwin v State, 857 So. 2d 249 (2003). State v. Ortiz, 504 So. 2d 39: a 4" folder may be a concealed weapon because determination of "common pocketknife" is a jury question. Folding knives must be carried closed: Walls v State 730 So. 2d 294 (1999), Porter v State 798 So.2d 855 (2001). A tactical knife may not be a "common pocketknife": J.D.L.R. v State 701 So. 2d 626 (1997). There is plenty of other interesting caselaw: 504 So. 2d 39 (1987); Nystrom 777 So. 2d 1013; State v. A.D.H., 429 So. 2d 1316 (1983); Simmons v. State, 780 So. 2d 263 (2001); Garcia v State, 789 So. 2d 1059 (2001). For legal status of icepicks and razors, see State v. Tremblay, 642 So. 2d 64 (1994) and Robinson v. State, 547 So. 2d 321 (1989)
