It's been a while since we had a good mystery tool. I picked this one up today as part of a package deal at a garage sale. The other tools that sat next to this were molding planes (that's what I was really after), two Stanley traditional planes, and a cobbler's hammer.
I looked through my American Dictionary of Hand Tools and couldn't find a match.
It is not particularly sharp and is heavier than it looks. The handle end is weighted, like it is full of lead or something. No moving parts. Total length is about 7 inches.
What do you think? A cobbler's tool? Something to stretch fabric? Any ideas at all?
