    摘要： A handle for a utility knife includes a housing made up of two or more portions. In one embodiment, a manually operable member for use in releasing the blade is retained to at least one portion of the housing and does not become separated from the housing when the housing is in an open state. In another embodiment, a catch for engaging the blade extends from a support member that is slidably movable within the housing. In another embodiment, the housing is formed of metal and a nose portion is formed of a metal that is more wear resistant than the rest of the housing, in order to improve the durability of the nose portion. In another embodiment, a bail screw is captured on a first housing portion and threadedly engageable with a second housing portion for (i) releasably securing the first and second housing portions in a fully closed state and, in turn, releasably securing a blade within the blade opening, and (ii) manually positioning at least one of the first and second housing portions in at least one intermediate state between the fully closed state and a fully opened state to, in turn, permit the blade to be manually moved through the blade opening.

    摘要翻译： 用于实用刀的手柄包括由两个或多个部分构成的壳体。 在一个实施例中，用于释放刀片的可手动操作的构件被保持在壳体的至少一个部分上，并且在壳体处于打开状态时不会与壳体分离。 在另一个实施例中，用于接合刀片的卡扣从可在壳体内可滑动地移动的支撑构件延伸。 在另一个实施例中，壳体由金属形成，并且鼻部由比外壳的其余部分更耐磨的金属形成，以便提高鼻部的耐久性。 在另一个实施例中，吊环螺钉被捕获在第一壳体部分上并与第二壳体部分螺纹接合，用于（i）可释放地将第一和第二壳体部分固定在完全关闭状态，并且可释放地将叶片固定在 刀片开口，和（ii）在完全关闭状态和完全打开状态之间手动将至少一个第一和第二壳体部分定位在至少一个中间状态，从而允许刀片被手动地移动通过刀片 开放
