In the spring of 2002, an object of regular shape was found during home gardening in the village of Tychów Nowy, comm. Mirzec, distr. Starachowice, woj. świętokrzyskie. The object had regular trapezoidal outline in plane, with a slightly oblique and rounded butt, and a damaged cutting edge (Fig. 1). The majority of the surface of the object, apart from the dihedral side, show clear traces of multidirectional polishing which also covers the area of the butt. The tool was made of the chocolate flint. We are dealing here with a knife-like form – a kind of backed knife, which in its final shape could have been also used as an axe. Taking into account the original function as a backed knife, the dating of the object should be narrowed down to the Early Bronze Age, most probably to the Mierzanowice Culture.
