    • A cutting device includes (i) a housing having first and second separable portions, the first portion having a locking aperture, the second portion having an attachment aperture, and (ii) a locking apparatus for removably locking the first and second portions of the housing. The locking apparatus includes an attachment portion for being fixedly attached in the attachment aperture, and a locking arm adapted to be releasably locked into the locking aperture. The attachment aperture and locking aperture are correspondingly positioned so that the locking arm becomes aligned with the locking aperture when the first and second portions of the housing are aligned for assembly. The housing may be constructed of metal, and the locking apparatus constructed of plastic. The locking apparatus may also include a return spring and blade carrier integrally molded therewith.

    • A metallic housing utility knife and method for making the device with a soft over molded elastomeric cover to provide blister free comfort and slip proof safety. The cover or skin is molded into the unique structure of the housing in a fashion that results in mechanical bonds that embrace the cover on the housing. The knife includes flexible posts from the cover that project into the blade storage compartment of the housing to prevent internally stored spare blades from moving within the storage compartment. An elastomeric blade clamp integrally formed with the cover serves to restrict lateral movement of blades of varying sizes when installed in a cutting position within the knife assembly. A rear quick release latch and interlocking housing sections provide a convenient way to open and close the knife and assure that it is also secure and firmly held when locked in a safe cutting position.
    • 一种金属外壳实用刀和方法,用于使该装置具有柔软的过模制弹性体盖,以提供无泡罩舒适性和防滑安全性。 盖子或皮肤被模制成壳体的独特结构,其结果是机壳接合壳体上的盖子。 该刀包括从外壳伸出到壳体的刀片储存室中的柔性柱,以防止内部存储的备用刀片在储藏室内移动。 与盖一体形成的弹性叶片夹具用于在安装在刀组件内的切割位置时限制不同尺寸的叶片的横向运动。 后部快速释放闩锁和互锁壳体部分提供了打开和关闭刀具的便利方式,并且确保当锁定在安全切割位置时它也是牢固且牢固地保持的。
