A device for removing staples from papers, cloth, or other material without tearing or mutilating the material. The device utilizes a heel of palm to finger gripping action to facilitate a more natural action for removing staples. Staples are extracted by way of a jaw which opposes a wedge-shaped piece (16) to an abutting plate piece (21), which straightens the staple while simultaneously pulling it out of the paper in a perpendicular direction. The wedge-shaped piece (16) includes a portion where its width and thickness increase to dimensions wherein the sum of the width plus twice the thickness exceeds the total length of the three sides of the staples being removed, thus facilitating complete extraction.

Dégrafeuse utilisable sur du papier, du tissu ou autre support, sans déchirer ou mutiler la matière. Par une préhension entre le creux de la paume et les doigts de la main, on rend l'extraction des agrafes plus naturelle. Cette extraction est réalisée par une mâchoire, qui oppose une pièce cunéiforme (16) à une plaque attenante (21), l'opération consistant à redresser l'agrafe et à l'extraire simultanément du papier dans une direction perpendiculaire. La pièce cunéiforme (16) comporte une partie où sa largeur et son épaisseur augmentent dans des proportions telles que la somme de la largeur et du double de l'épaisseur dépasse la longueur totale des trois côtés de l'agrafe extraite, ce qui facilite une extraction complète.
