While fishing the other day I found this on the ground. I'm think it's a fishing tool for tying knots but I might be wrong.

That's the smallest pig castrator I have ever seen.

Could be a type of hook remover .

Hook remover?

I would use a tool like that for tuning crankbaits

I don't believe that tool is a hook remover. More of a tying tool or a tool used to adjust crankbait like was stated above.

Noice…lol

Issue around here when you buy gallons of paint. For popping the lid off

Tuning hand saw blades possibly??

That slot and circle opening looks like an old saw set used to bend the saw teeth left and right so they cut a wider kerf than the saw body. But it's to small to be much use for that so I'm going with crankbait tuner considering where found.

Might it also be some sort of fid ?

I had one of them before but I have no idea it's intended purpose. I can tell you its soft metal and if you use it with any force it'll break easily.

Looks like someone took their wife or girlfriend fishing and they got bored while waiting. It seems she decided to push the cuticle on their finger nails while sitting around. Then dropped the tool without realizing it.

I don't think anyone has nailed it yet.
I hope someone does as I have on in a tackle box that I picked up at an auction some time back.
Been wondering ever since.

Will be watching ..... and researching a bit.

As you were,
Thanks
