Patent abstract

An out the front assisted knife has a casing, a blade and a secondary pusher. The casing has a secondary channel hole formed through the casing, extending axially, and disposed away from an axial inner end of the casing. The secondary pusher is axially movably mounted in the casing, protrudes out of the secondary channel hole of the casing, and axially abuts against the inner end of the blade. The secondary pusher is disposed away from the axial inner end of the casing, such that the user's hand holds at least half of the casing when pressing the thumb on the secondary pusher to extend the blade. Therefore, the user can hold the knife by the center of gravity of the knife, and thus can stably and conveniently operate the knife, thereby preventing the knife from dropping accidentally.
