When you strike this device with a hammer, it applies the impact, as
well as turning force at the same time. Very effective. Japanese
motorcycles used to have steel Phillips head screws holding on the
aluminum engine parts. This tool could get them out, even of the screw
heads were already partially rounded out from previous attempts.

Absolutely correct! Still have mine I bought in the '70s to pull the
screws out of my Kawasaki. Works like a champ.
