The invention relates to a device for sharpening the blade of a manual cutting tool, in particular a knife. The respective side panel is formed by a bridge member having a first longitudinal edge portion attached to the first body panel and a second longitudinal edge portion attached to the second body panel, the bridge before use of the article being folded in an accordion-like fashion and can be extended and unfolded when the article is to be used so as to form the side panels of the article. , a major surface having a recess not extending through the substrate, and a material having a modulus of elasticity less than 10 GPa disposed within the recess. The lenses and the at least one spatial light modulator are configured to selectively form a high intensity optical spot to focus atoms from an atomic beam onto the substrate. By increasing the number of robots, the efficiency in completing the task is also increased.
