This tong is my rivet-less, adjustable style (RA Tong). This slip joint style tong can hold within a much wider range than a standard tong. But it is not intended to replace size/shape specific tongs. Those thinking to use this as a universal tong may find this style frustrating. I have found this style to be more of a fill-in-the-gap tong, good for in-between sizes or when a workpiece changes shape to the point where size specific tongs will no longer hold.
