One side is solid, polished, and has a yellow-gray color (front side). The back side is covered with spongy material which is turning into solid bone at 100 mm from the lower end. The blade is made of quartzite inserts of rectangular or square shape. One edge remained 28 inserts, the other one remained 45 inserts. The slots has a cross section of triangular shape. The handle is broken on two holes. Their diameter is not more than 5 mm.
Both sides of the dagger have an ornament. It is a row of drilled points adjacent to each other and located along the centeral axis. The row of points end 35 mm to the tip. The row of points also has three rhombus located near each other at a distance of 256-291 mm from the tip. On the left edge, opposite the middle rhombus, three V-shaped notces are drilled.
