A cutlery part, in particular a spoon, fork, spork or knife, which is configured so as to be variable in length and is unfoldable from a shortened and folded storage position into a position of use which is extended with respect thereto, and is formed from a planar blank with an upper side and an underside, the cutlery part comprising - a rear end and a front end spaced therefrom in the direction of its longitudinal extension, wherein a longitudinal axis extends between the two ends (5, 6), and the front end forms a cutlery part head, - a first embossing line, which first embossing line is aligned in the transverse direction with respect to the longitudinal axis of the blank and divides the blank into a first cutlery part section and a second cutlery part section, wherein the first cutlery part section extends between the rear end and the first embossing line and the second cutlery part section extends between the first embossing line and the front end, wherein the first embossing line forms at least one fold line, and - a locking device comprising a first locking element and a second locking element cooperating therewith in the folded storage position, wherein in the storage position and when the first and second locking elements (14, 15) are in locking engagement with one another, the first cutlery part section and the second cutlery part section are held releasably against one another, - wherein the first locking element is arranged in the region of the first cutlery part section and the second locking element is arranged in the region of the second cutlery part section, and - wherein the first locking element is defined by a first material separation passing through the blank in the direction of its thickness, characterized in - that the second locking element is defined by a second material separation passing through the blank in the direction of its thickness, and - that the material separations (16, 17) each have a longitudinal course extending essentially in a parallel direction with respect to the longitudinal axis. - a rear end and a front end spaced therefrom in the direction of its longitudinal extension, wherein a longitudinal axis extends between the two ends (5, 6), and the front end forms a cutlery part head, - a first embossing line, which first embossing line is aligned in the transverse direction with respect to the longitudinal axis of the blank and divides the blank into a first cutlery part section and a second cutlery part section, wherein the first cutlery part section extends between the rear end and the first embossing line and the second cutlery part section extends between the first embossing line and the front end, wherein the first embossing line forms at least one fold line, and - a locking device comprising a first locking element and a second locking element cooperating therewith in the folded storage position, wherein in the storage position and when the first and second locking elements (14, 15) are in locking engagement with one another, the first cutlery part section and the second cutlery part section are held releasably against one another, - wherein the first locking element is arranged in the region of the first cutlery part section and the second locking element is arranged in the region of the second cutlery part section, and - wherein the first locking element is defined by a first material separation passing through the blank in the direction of its thickness, characterized in - that the second locking element is defined by a second material separation passing through the blank in the direction of its thickness, and - that the material separations (16, 17) each have a longitudinal course extending essentially in a parallel direction with respect to the longitudinal axis.
