lever style kindling splitter

Anyone ever tried one of these?

I haven't myself, but I do recall Wranglerstar on Youtube reviewing one. He also reviewed a kindling splitter that was a tapered screw for a cordless drill, like the old rail-splitters, only in miniature. It was hands down the fastest, and appeared to be more versatile.

I think this is worth looking at
It can be used by anybody, it can be used sitting or standing
It just depends on the post height you mount it on.
Invented in New Zealand by a young woman.
Copied everywhere since!
