Abstract: When thinning scissors, in which the cutting edge of at least one scissor blade is serrated and the cutting edge of the other scissor blade is, for example, smooth, are used, visible steps detrimental to the appearance of the hair-style are obtained during thinning. To prevent the steps from being visible in the finished hair-style, one scissor blade of the thinning scissors has, on its outer side, a serration with stub teeth which overlies its cutting edge at a distance from the latter, the individual teeth projecting relative to the cutting edge of the scissor blade and having differing lengths.
