A handheld stamper with an abrasive element. The handheld stamper includes an actuator mounted to a base, a stamping die coupled to one of the actuator or the base, and an abrasive element affixed to a surface of the handheld stamper. The handheld stamper is used to protect sensitive information, such as text, by using a combination of abrading the text with the abrasive element and imprinting an obscuring pattern over the text. To obscure the sensitive information, a medium, e.g. ink, forming the text is first abraded with the abrasive element to distort the medium. The abraded text is then stamped with the handheld stamp to sufficiently obscure the sensitive information.
