Abstract
A folding knife includes a handle having a blade channel, a blade rotatably coupled to the handle, and annular blade seals coupled to either side of the blade between the blade and inner surfaces of the blade channel. A locking mechanism having first and second control pins coupled to the blade within the circumference of the blade seal so as to extend toward the first handle element. A lock plate is movably coupled to the handle and engages the first and second control pins when the blade is in the open and closed positions, respectively. A release knob coupled to the lock plate allows a user to move the lock plate to release the blade. A seal positioned between the release knob and the handle seals a space between the release knob and the handle.
Claims25
A folding knife, comprising:
- a handle including first and second handle elements;
- a blade coupled to the handle and configured to rotate around a pivot axis between an open position, in which a sharpened edge of the blade is exposed, and a closed position, in which the sharpened edge of the blade is positioned within a space between the first and second handle elements;
- and
- a first blade seal positioned between the blade and the first handle element.
A folding knife, comprising:
- a handle having a blade channel;
- a pivot fastener coupled to the handle and extending across the blade channel;
- a blade positioned in the blade channel of the handle and coupled to the pivot fastener, and configured to rotate about the pivot fastener between an open position and a closed position;
- and
- a first seal positioned between the blade and a surface of a first sidewall of the blade channel and configured to substantially prevent contaminants from entering a space surrounding the pivot fastener between the blade and the first sidewall of the blade channel.
A folding knife, comprising:
- a handle having a blade channel formed therein;
- a blade coupled to the handle so as to be rotatable between an open position, in which the blade extends away from the handle, and a closed position in which the blade is received in the blade channel;
- first and second control pins coupled to the blade so as to extend from a first side thereof;
- and
- a lock plate having a notch formed in a first end, the lock plate being movably coupled to the handle such that, while the blade is in the open position and the lock plate is in an engaged position, the notch engages the first control pin and resists movement of the blade away from the open position, and while the blade is in the closed position and the lock plate is in the engaged position, the notch engages the second control pin and resists movement of the blade away from the closed position.
