Full Speed Ahead ISIS Bottom Bracket Tool
As the name implies this is the tool you'll need to remove and/or install an ISIS bottom bracket. It's also compatible with Shimano Octalink bottom brackets.
You'll need to use a 1/2 socket drive to make this tool work. There is no spot for an adjustable wrench.
On the off chance your bare hands have a superhuman torque rating of at least 400 inch pounds, feel free to disregard the part about needing a socket wrench.
