    • A multifunctional device for removing material from an edge of an object and lifting an object from a support surface is provided. The device includes front and rear portions that are positioned at an angle relative to one another to form a pivot point. The front portion is positioned beneath the object while a user applies a downward force on the rear portion to rotate the device about the pivot point to lift the object from the surface. A pair of opposed sidewalls extend from an upper surface of the device and a top wall is coupled between the sidewalls to form a channel. At least one protrusion extends from the top wall into the channel to remove material from the edge. In addition, a tab may extend into an aperture formed in the rear portion to engage and assist in the removal of a lid from a bottle.
    • 提供了用于从物体的边缘去除材料并从支撑表面提起物体的多功能装置。 该装置包括相对于彼此以一定角度定位以形成枢轴点的前部和后部。 当使用者向后部施加向下的力以使装置围绕枢转点旋转以将物体从表面提起时,前部位于物体的下方。 一对相对的侧壁从装置的上表面延伸,并且顶壁连接在侧壁之间以形成通道。 至少一个突起从顶壁延伸到通道中以从边缘移除材料。 此外,突片可以延伸到形成在后部中的孔中以接合并帮助从瓶中取出盖子。
