  • Publication number: 20040088865
    Abstract: A folding knife having a safety lock moveably mounted on a handle of the knife. The safety lock may slide to a locking position to prevent the blade from opening out of the handle by obstructing the path of the blade as the blade is urged from a closed position to an open position. The safety lock also may slide away from the locking position, in which the safety lock does not obstruct the path of the blade.
    Type: Application

  • Patent number: 6427334
    Abstract: A folding knife having a blade pivotally connected to an end of a handle so that the blade is rotatable about a pivot axis between an open position and a closed position. In the open position, the blade is extended away from the handle. In the closed position, the blade is at least partially received within the handle. The knife also has a locking mechanism that is movably secured to the handle so that it may be moved into a locking position. When in the locking position, the locking mechanism blocks a protruding member extending transversely outward from a surface of the blade to prevent the blade from being rotated from the open position to the closed position.

  • Patent number: 6397476
    Abstract: This invention relates to a mechanism in a folding knife that urges the blade to move to an open and alternatively to a closed position. The knife generally consists of a blade having a tang extending outwardly from the blade; a handle having at least one recessed portion; a bar pivotally connecting the tang and the handle; and a bias element engaging the blade wherein the bias element is housed within the recessed portion of the handle. Generally, in the present invention, the blade must be moved manually a certain distance whereupon the mechanism serves to complete the movement of the blade without the application of further outside force by the user.

  • Patent number: 6378214
    Abstract: A folding knife having a blade with a tang, and a handle with an end to which the tang is pivotally connected. The blade is rotatable relative to the handle about a pivot axis between an open position in which the blade is extended away from the handle and a closed position in which the blade is at least partially received within the handle. The folding knife may also include a post slidably held by the blade to slide along at least a portion of the blade between a retracted position and a locking position. When the blade is open and the post is in the locking position, the handle and post block pivoting of the blade from the open position toward the closed position. Additionally, the folding knife may be provided with an oversized tang portion and a spring mechanism that allow the knife blade to be easily pivoted into the open position.
