tool design details

i saw this via core77 today: stanley's newest addition to the tape measure. why did no one think of this before??

The key difference is just a few fractions of an inch of metal added to the end hook, so not only can you catch surfaces above and below the tape, you can even hook it on the side--invaluable for when you're trying to measure off a wall corner and keep the tape horizontal so it doesn't collapse. Genius!
