This is an old tool I found that belonged to my father. The handle size would fit your hand.
The metal part is very thick and not sharp, but it might have been at one time.
Anyone seen this before? (This is not a trick question. I don't have a clue.)
Oh wow! That's cool you found a pic of one nancy, that is like it for sure, I'd say the same. Meanderer is probably right about different attachments!!
What's unusual is it has his name stamped on the other side. Led me to think it might have been a tool from where he worked---building tires in a factory.
He applied the plies before they had steel-belted radials. Or it could have been a gift from someone and they stamped his name on it.
