I am the oldest living male member of anyone in my and my wife's families. Lots of manly men have past down tools that are a total mystery to me and I have a big toolbox full of them in the garage attic. I figure it will be fun to post pics of oddball tools I own and use as well as those that are ??????? to me. I hope other guys will do the same. WAT DIS TOO?? It is labeled snap on and "no guar", it looks like a cobbled together flare nut wrench but is factory made so what is it for??? (044 impulse line for scale) 2 different snap on drivers said it was a factory specialty tool but no idea what for, apparently they used to make a lot of this type thing, I have a handful of others from them.
