There's a hybrid spork that's made of polycarbonate, it's a spoon, fork, and serrated knife:

I stumbled on it when I ordered a new bag from them. (By the way, if you're a fan of the BOB that Maratac has been making for County comm for years, they just released a larger version. It's now holding a bunch of goodies in the back of my truck.)

I've been using the Snow Peak Ti spork when backpacking for a couple years, pretty indestructable, light, and cleans up easily. Does get pretty hot, the composite material sporks are a little easier with hot stuff.
