The tool that is sticking up. It's about 8x3x15mmm, with slightly pointed edges.

8mm?
8 or 10mm would By my guess
it's for getting stones out of horses hooves.
Oh yes, it does fit an 8mm socket!
I think thats a space saving, and not very good 8mm hex key
Yeah, I can't imagine it will work very well with a tight 8mm bolt.
The SWAT tools are more for getting you home, so if your crank came loose you're able to tighten it up enough to get back.

On the other hand it's better for tightening a loose crank bolt out on the road than the 8mm you didn't take because it was too bulky.
It's a just in case tool, better than nothing.
yep, 8mm allen key bit
2x4mms can also be used.....
