The javelin point on display was fashioned from a metatarsal of a large animal such as deer, elk, or aurochs. The point’s cross-section is flat-and-convex at the base and oval at the tip. The surface features two rounded indentations. They held pieces of flint which together formed a sharp edge. The flints were fixed to the edge with a pitch, viscous substance obtained from wood. Remains of the pitch have been preserved on the point to this day. Archaeologists have managed to recreate the process of manufacturing of the tool. First, the bone was cut to obtain a flat, convex surface. Next, the sides of the point, the tip, and the slots for the flint were formed. Finally, the point was ground and polished smooth. The artefact was found by Edward Plewiński in May 1871 in the vicinity of the locality of Potwiecie, in peat by the river.
