1 - Why is this in techniques?!

2 - Blurry picture is blurry.

3 - It's an allen key (or allen wrench if you're an uncivilised yank), given that you don't know what it's for it's probably one of the ones they supply you with for adjusting the truss-rod in your guitar's neck.

4 - *reported*
R.I.P. My Signature. Lost to us in the great Signature Massacre of 2014.

Seriously, you don't know what a fuking allen wrench is? Give up the guitar NOW!

Well I never felt the need till today about knowing it and I've never used it.
Not a technique, silly enormous blurry picture and warnings for being twats - closed.

I'd have moved it to EG but I'm too embarrassed

If you've got any more questions about it either ask there or Google "Allen key"
Actually called Mark!
