What? No. None of that. Even if vines wrapped around a sharp stone were ever common, no one alive today (outside an uncontacted tribe maybe) is "familiar" enough with them to make a difference.

Texturing handles is just an obvious mechanical thing to increase grip that probably gets invented every time someone makes a handle from a smooth material.

I'd like to agree that it was a bit of a strange and incorrect comparison to make. Also, I may be incorrect here, but I thought skeuomorphism just refers to ornamental design cues, not functional design features.
