To create the decoration on the thimble from grave 11/2021, one simple impact tool with a blunt-needle point (a kanfarnik) was used. To decorate the thimble from grave 10/2021, a kanfarnik was used only to create punched rows on the body. The decoration on the top of the thimble is made more carefully, using a complex tool with an oval working end. A thimble from grave 16/2022 is allocated to a separate group, it belongs to a completely different production tradition.
