Abstract
A tool used in manufacturing circuit board holders from sheets of material has a working face for forming embossments on the sheets by repetitively striking the sheets therewith. The working face includes an H-shaped formation for forming two separate halves of an embossment on the sheet of material with one strike, of which, of the two separate halves, one is delimited by the upper parallel lines of the H and the other is delimited by the lower parallel lines of the H. In a method using such tool, the sheet of material is struck once with the tool, the working face of the tool is moved relative to the sheet in a direction of the parallel lines of the H by a predetermined distance, and the sheet material is again struck with the working face of the tool so that an embossment is formed on the sheet which is delimited by a pattern left on the sheet of material by the parallel lines of the H pointing in one direction at the first strike and by a pattern left on the sheet of material by the parallel lines of the H pointing in the other direction at the second strike.
