I just recently picked up a Benchmade Blue Box knife maintenance driver kit. This little thing is sweet! The back side has a pocket/belt clip on it. I don't ever think I'll carry this kit this way though... Everything encased within itself under a clear snapping lid. 2 bits of each of the common sizes and the magnetic bitholder/driver itself There is a hole in the bottom of the case itself, that the driver fits in. All in all, a very organized, convenient, minimal knife set that I think every knife nut should own. I can't believe I've gone this long without ever trying this thing!
