Default small blade

Australian hand-powered flight uses mulga wood which is one of the hardest timbers . Aboriginal mulga blade weapons are 2ft x 2inch x 1/2 inch. Maybe there are 2ft prop blades which are 1/2 inch thick but maybe generally not that thin. Perhaps a large model-plane prop could be 1/2".

This question is on the fringes of "propellors".

So if these thin props exist , are there any cases of injury to the skull by a prop with the type of bone-fracture known? One girl in Texas had a head wound but didn't reply to me . An ancient skull has been found with a sword-cut , explained as being by mulga blade , but I don't believe it . There's jail time for testing on a person . Any comments on what a prop does to skull?
