Is The A Shaft Straitening Tool??

[Arsenal]

I stumbled on this rock which appears to be a straightener or something of that nature. I was in Travis County and found this in a honey hole inside the Greenbelt.

Thanks in advance.

That's actually a modern Van Halen guitar pick.

I'm not sure about the rock... interesting. Similar to a net weight but not quite. Is there water nearby?

Why would there be water by my guitar? :-)

Yeah, I found it in a creek bed feeding the Colorado River. Thanks for the laugh.
