This goofy little tool is to protect your O-ring from getting sliced on the threads when installing them on a case through-bolt. In my case rebuilding a Porsche 914-6 (aka 911T) engine.
I got the idea from a tool I saw offered by a professional tool outfit called Stomski Racing.
Slightly revised design for better print.
