A foldable knife includes a handle and a folding blade. The blade is pivotable about an axis between a folded position and an extended position such that a sharp edge enters the handle when it is folded. The knife also includes a mechanism for releasably locking the blade in its extended position and for applying resistance to the blade in its folded position. The mechanism includes a ratchet member having at least two notches formed therein. The ratchet member is connected to the blade. The mechanism also includes a pivotable locking lever for engaging the ratchet member for locking the blade in its extended position and for applying resistance to the blade when the blade is in its folded position. The locking lever has a extending portion that extends from the front edge of the handle so that it may be manually manipulated to disengage the locking lever from the ratchet member to release the blade from its extended position.
