Maybe. If it looks like a "dirk", a short, double-edged short sword or long knife with a point designed as a stabbing weapon, then the answer is "no". Note that I didn't say it IS a dirk, but is LIKE a dirk. The concealed weapon statute prohibits dirks, bowie knives, ballistic knives, switchblades and razors and things that are "like" any of those. Open carry should be ok, but it's illegal to transfer possession of it to a minor.
