This is the LEGO Swiss Army Knife built by LEGO CUUSO user Robiwan. That's a pretty clever design. Still, you should never, under any circumstances, bring a plastic knife to a ninja sword fight. I know you might fancy yourself some kind of MacGyver that doesn't need anything but a Swiss Army knife to defeat a group of ninjas, but you're wrong. You're gonna get both your arms cut off. Then wake up and be thankful it was just a dream. Then wake up from that dream in the hospital with no arms.
Thanks to bryce, who got mega bummed after losing the toothpick and tweezers from his Swiss Army knife.
