发明名称 Locking mechanism for a push button activated folding tool
摘要 A folding tool with an improved locking mechanism is provided. The locking mechanism includes a biasing member interconnected to a handle of the tool and coupled to an engagement member, which may be a push button. In various embodiments, the biasing member biases the engagement member towards a locked position in which a portion of the engagement member interacts with a tang of an implement to prevent rotation of the implement.
