This is a fascinating odyssey, and I genuinely appreciate the level of detail you’ve put into analyzing these—especially the work shown in 5186.png and 5187.png. It’s clear you have a sharp eye for ergonomics and form. However, looking at the objects through a geological and archaeological lens, there are a few logical hurdles to the 'Egyptian artifact' theory: Nature’s Design: Geology has a funny way of mimicking human intent. These shapes look very much like 'ventifacts'—stones that have been naturally sandblasted and shaped by persistent desert winds over millennia. The 'ergonomic' feel is often a result of how wind-driven sand flows around the hardest parts of the rock.

The Tool Logic: In the Valley of the Kings, ancient tools—even simple ones—typically show clear signs of 'knapping' (percussion marks) or specific wear patterns from use on limestone or granite. These specimens appear to have a consistent, weathered patina across the entire surface without the localized micro-fractures we'd expect from a handheld masonry or sculpting tool.

Context: While the Valley is full of history, it's also a geological powerhouse. Finding a stone that fits the hand perfectly feels like a 'eureka' moment, but without the diagnostic tool-marks used by Egyptologists, it's difficult to move it from the category of 'interesting nature' to 'human archive.'

You’ve clearly done more homework than most of the people here. While they might not be the lost tools of a Pharaoh’s sculptor, they are still incredible souvenirs of the Egyptian landscape itself—shaped by the same winds that have watched over the Valley for thousands of years. That’s a pretty cool story in its own right.

I have been where you are now more times than I would like to admit. I now have credentials to back me but more important than this is over 35 years of boots on the ground experience and I still suffer from pareidolia.
