In the JetBlue terminal at JFK, they had amazing spoons:
I'm not sure what makes them "multipurpose" since they basically looked like normal plastic spoons:
Notice that the knives, however, are not multipurpose. So, maybe you are only allowed to use the knives for cutting, but you can use the spoons for stirring tea (or coffee!), eating soup (or chili), launching peas (or grapes), as guitar (or banjo) picks, backscratcher...
This was my first time flying JetBlue, and I must say: They have the most amazing planes:
0 mph, parked at the gate, and yet the plane was still at 5 feet of altitude! More incredible, though, was our plane back from Texas:
It reached 420ft while parked at the gate! If they have worked out the secret to antigravity hovering planes, no wonder they can afford to provide multipurpose spoons instead of those cheap single-purpose ones the other airlines have.
