The Pro-Tech Malibu Flipper knife flies open with precision with no springs so it's a legal carry...Like in Malibu! It's plunge lock with a reverse tanto blade or wharncliffe blade depending on which style you choose. We're sorry these are no longer in stock. If you're interested in one email us at email@example.com and we'll be happy to let you know when we have them available again. Let us know which handle color and blade style you would like.
