Present day tool-holders or tool-holder systems for general work-shop or hobby-room use are generally manufactured from a large number of different blanks, e.g. one blank for each tool-holder configuration. This invention relates to tool-holders manufactured from a respective one of three starting blanks or strips cut therefrom and having arranged therein at least two mutually adjacent rows of openings. The openings of one row may be of greater area than the openings of the other row, or an opening of a given row may be of greater area than another opening in said row. A blank is cut and/or folded in a particular manner to form a holder for supporting a variety of tools, such as hammers, screw-drivers, and holemaking or piercing tools, or for supporting a single kind of tool.
