Hardened wood 23x harder than natural wood
Obsidian, ceramic and hardened wood knives all sharper than steel knife.
So if erectus had a time machine, giving it access to knowledge and
equipment that didn't exist until 2021, they were probably running around
with wooden knives that were nearly 3x sharper than steel!
But they didn't have steel either...
So if they had access to modern knowledge, chemicals & equipment, and
lord knows we have no reason to doubt that they did, they they were
comparing their non-existing hardened wood to something else that didn't exist...
And yet people STILL think pale anthropology is a joke! Imagine that,
