发明名称 Steel staple remover
摘要 A hand tool for aiding in the removal of heavier, steel type staples normally used for binding a relatively large number of pages together including a handle with a steel tube having a uniquely shaped working end extending therefrom to allow it to be inserted under the bent end portions of a U-shaped clinched staple and pivoted upward causing bent portions of the staple to straighten thereby allowing the stapled work to be more easily separated.
