On the left, the stone dagger with a two-stepped handle is presumably made of polished sandstone. It was firstly found in four pieces and also no dagger peak, but later restored for the exhibition. It has the very sharp blades with two blood lines. Its semi-shaped head is brattishing and also similar to the stairs, providing more artistic values to its own decorative character. (L 41.8cm, W 7.8cm, T 1.0cm)
Although the dagger in the middle is the quite similar style with the left, its blade looks a bit looser due to some damages at the peak. It is worth noting that the neck part has divided into two sections with a narrow waist. (L 33.7cm, W 7.8cm, T 1.7cm)
Round-shaped stone tool on the right seems to be made by sandstone but it is difficult to assume what the tool was for. It is well polished with one hole in the middle. (D 8.0cm, T 4.0cm)
