There is some rather fanciful cross wedging depicted in those patent drawings!

A lot going on with that patent. Not sure just putting ribs in the eye would be patent infringement.

Have any of you seen any original crosswedging like that in the wild?

Also, for some reason I think the inventor's name of Harry B. Stump is a fitting name for an axe attachment system.

I certainly haven't. Nor do the NOS or original handle versions of Wood Slashers that have been featured/exhibited on here have anything more than a single wedge.
 
I acquired an axe today with a patina on it. I sanded it down and it has a B39 stamp with remnants of red paint on both sides.No other markings I can find. It also has 4 ridges inside of the eye. The handle is a forest king which I’m almost certain is a replacement, it is not hung that well. Does anyone think it might be the Kelly woodslasher? Here are some pictures.
