A reusable paperclip can accommodate a large range of paper stack sizes. It is configured to bind a stack from one corner without becoming distorted in shape when used on a large stack. The clip has vertical members to prevent horizontal and vertical movement of the stacked papers and connected horizontal members to apply pressure to the surfaces of the stack to frictionally bind the stacked papers. The clip is easily placed and removed by the user, and allows a person to view all information on a standard formatted page with little to no obstruction of the printed information. The clip also allows a user to flip though a stack of papers and easily remove individual papers from the stack or insert additional pages without disturbing the sheets and without the need to remove or adjust the position of the clip.

A method of making a book or booklet cover including placing a first face of a sheet-like information carrier on a first side of a metal sheet that extends beyond one edge of the sheet-like information carrier. The method including bending a portion of the metal sheet along an edge thereof, for the portion to elastically press on the sheet-like information carrier. A book or booklet cover including a metal sheet supporting a sheet-like information carrier, which sheet-like information carrier has a first face and an opposite second face, with the second face on a first side of the metal sheet, the metal sheet-having a portion extending beyond at least one edge of the sheet-like information carrier, where the portion of the metal sheet has a rounded bend along an edge thereof, the portion elastically pressing against the sheet-like information carrier.

A clip-less clipboard device is disclosed having a clipboard surface having: a first planer surface area; a second planar surface area generally parallel to the first surface area and generally equidistant apart from the first surface area at a predetermined distance; a plurality of flutes disposed within the first surface area and the second surface area and generally perpendicular to the first surface area and the second surface area; and a corrugated core disposed within each of the plurality of flutes, thereby to create a plurality of hollow channels within the flutes within the first surface area and the second surface area, and wherein each channel runs a continuous length within the first surface area and the second surface area; and a slit defined on the first planer surface area of the clipboard surface and configured to hold an article of paper upon the first planer surface area.

A binder clip includes a generally triangular clamp, a catch arm, and a hook arm. The catch arm includes a linear segment having a catch width, and the hook arm includes a hook configured for secure but releasable connection around the linear segment of a matching binder clip. The hook has a hook width less than the catch width of the linear segment.

A binder clip includes a generally triangular clamp including a first side between a mouth and a first vertex, a second side between the mouth and a second vertex, a third side between the first vertex and the second vertex, a first wing extending away from the mouth to a first wing end, and a second wing extending away from the mouth to a second wing end such that the first wing and the second wing are substantially coplanar. The binder clip further includes a first arm pivotably connected to the wing at the first wing end, and a second arm pivotably connected to the wing at the second wing end, the first arm and the second arm cooperatively useable to open the mouth.
