LEGO Swiss Army Knife
The LEGO Swiss Army Knife! It's not for sale yet, but if you like it, vote the Technic-Bionicle creation into official company review over at LEGO CUUSOO (the strangest and most cumbersome name for a Website I think I've ever heard, by the by. Yeah, yeah, I know it's Japanese or whatever, but it's got too many vowels and TOO MANY CAPS.)
Brick master Robiwan Kenobi built the LEGO knife with 4-utensil functionality; the blade, file, and screwdrivers all unfold and...well, I guess that's about it.
