The Tri-Lobed Disc in the Tomb of Sabu and the Basins at the Sun Temple Were for Beer | Akio Kato | Kanagawa University | DOI: 10.4236/ad.2022.101002Abstract: We propose that the Tri-Lobed Disc excavated from the Tomb of Prince Sabu (about 3000 BC, First Dynasty) was used in brewing beer as a mash rake to mix and even out the mixture of grains and hot water in a fairly big mash tun. Two observations which support this idea are presented in Section 1, and why the Disc works efficiently in mashing is explained in Section 2. We also propose in Section 3 our idea about how the Tri-Lobed Disc was made, and actually made its metal model to experiment and observe the flow around the Disc. About a would-be big “royal” mash tun of Prince Sabu is discussed in Section 4, and as a by-product of searching for any remains of ancient Egyptian mash tuns, we uncover in Section 5 that the large basins at the Sun Temple of Nyuserre (about 2400 BC, Fifth Dynasty) were such remains for ritual beer brewing. This reinterpretation succeeds in explaining almost all of their functions.
Kinda looks like it’s for making rope
Regardless of its usage which is not known despite the article’s claim, how was it made using pounding stones, copper chisels?

“The Disk is made from a fragile, weakly metamorphic siltstone [ 6 to 7 on the Mohs scale; same harness as granite ], also referred to as metasiltstone or schist, a brittle rock that would have been extremely difficult to carve with the precision observed, especially given the intricate design and delicate nature of the material.”
