Abstract:
1. A knife, comprising: a handle; a blade coupled to the handle so as to be movable between an open position in which the blade extends from the handle, and a closed position, in which the blade is received within the handle; a bias member operatively coupled to the knife and configured to provide an opening-assist to the blade; and a bias member engagement mechanism switchable between an engaged condition, in which the bias member provides an opening force to move the blade toward the open position only after the blade is manually rotated from the closed position to beyond a threshold point, and a disengaged condition, in which the bias member does not provide an opening force to move the blade as the blade is moved from the closed position to the open position, the engagement mechanism including a wheel extending from a surface of the handle, a position of the wheel controlling whether the engagement mechanism is in the engaged or disengaged condition.
