Please help me identify this tool.
 

I got this with a lot of tools that I purchased, and really have no idea what it is for. Anyone know? (The plier like tool not the ruler:))

Thanks.

That's a pair of lockring pliers for the lockrings on traditional cup and spindle BBs. It was used in conjunction with a pin spanner to tighten/remove the left (adjustable) cup.

I still prefer it to the hook spanners because it never slips and with a bit of touch I can turn the lockring in either direction in either direction without moving the cup, or bind them so they turn together, making fine tuning the adjustment easier.

It;s also great for track lockrings, but doesn't work so well when the sprocket overhangs the lockring.

VAR lock ring pliers.

Not sure but it looks like an adjustable bottom bracket lockring tool. Well that is my guess.

Some kinda proctology tool.

Just what I needed to know, Thanks for all of the replies.
