Abstract: A method for producing a key (50), wherein a data set (40) of a key is obtained by recording the surface of the key (10) and subsequently performing a data optimization (55), or from data of a data collection (46), in order to produce the key (50) from a semi-finished product clamped in a machine by a computer-controlled production method (9), wherein at least two different locking features are introduced into the semi-finished product.

Abstract: In a method for producing a paper pen/pencil (19), the following steps are carried out: a lead/reservoir (12) is introduced into a receptacle (14, 21, 23, 28, 29, 34, 38); the lead/reservoir (12) is secured within the receptacle (14, 21, 23, 28, 29, 34, 38); and the receptacle (14, 21, 23, 28, 29, 34, 38) is connected to paper (1).

Abstract: In a method of producing a key blank from a workpiece (6) using at least one tool, in particular a milling cutter (3′) of a milling device, profiles are incorporated in the workpiece (6) as grooves (2.1′-2.5′), recesses or the like, predetermined, copied or sensed profiles (2.1-2.5) being converted into profiles (2.1′-2.5′) in accordance with the geometry of the tool(s) used, in particular of the milling cutter(s) used.
