A foodiform tool is any tool shaped like the food
it is used with. For example, a mushroom brush
shaped like a mushroom. Or a lobster cracker
shaped like a lobster claw. Or corncob holders
shaped like little corncobs.

Can you think of any others?

I think foodiform tools appeal to people who lust
for a peculiar form of consistency in their lives.
All of their tools would be foodiform tools, if
such were available. They would cook hotdogs in
a cooker shaped like a big hotdog. They'd store
milk in a bottle shaped like a cow. Their coffee
grinder would be shaped like a big coffee bean,
and their coffee brewer would be shaped like a
coffee cup.

I call this form of insanity foodiformia.
