A spoon, at least most plain spoons, have a continuous, smooth surface. Most forks have three or four tines set close to each other. Electrons excited by the microwaves in the metal seek a way to leave the metal. If there is another conductive surface close to the surface where there is a build-up of excited electrons, the electrons will arc over to that other surface. Tinfoil will do the same thing if it is not completely flat. My microwave has a metal rack in it, but I suspect that the racking is wide enough apart to prevent arcing between the metal rods.

Technically, most new microwaves can handle a bit of aluminum, but NOT anything with pointy edges (they act like antennas and cause electrical arcs in the microwave.) However I'm pretty sure that most forks and spoons are made of stainless steel, which cannot go into the microwave, points or no points.

It is not a good idea to put any metal in a microwave

U should never put any metal in a microwave as it can reflect the energy back into the magnetron and burn it out.

You can't put any metal in the microwave as far as I know! (I figured this out the hard way)!

you cant. if they're plastic then it'll melt, if they're metal then lead will come out.
