Abstract
A folding knife with a locking mechanism is provided. The folding knife includes a locking spring that interfaces with a recess in the blade to bias the blade from being pivoted out of the handle. A button interfaces with the locking spring to actuate the locking spring interfacing with the blade.
Claims23
A folding knife comprising:
- a handle;
- an internal cavity defined by the handle;
- a blade rotatably coupled to the handle, the blade rotating with respect to the handle into and out of the internal cavity between a retracted position and an extended position, the blade defining a recess;
- a sliding lock slidably coupled to the handle;
- and
- a locking spring coupled to the handle, a first end of the locking spring interfaces with the recess when the blade is in the retracted position, the locking spring comprising a second end opposite the first end and a contiguous body that extends from the first end to the second end, wherein the second end is rigidly coupled to the handle, the locking spring interfaces against the sliding lock and biases the sliding lock away from a tip of the blade when the blade is in the retracted position.
