Shark tools promt from Draw a box

This is a prompt they give in draw a box, so I thought about giving it a try :)

quote from ~Imposter~ from Draw a box

TOOL SHARK!

You've all heard of the hammerhead shark - clearly the result of Poseidon leaving a mallet alone in the sea too long, and life finding a way. But what about the rest of his workshop? No mistake is destined only to happen once - so what strange sharks came out of his other tools?

Take a tool or utensil - you're not just limited to workshop items, consider tools that might be used in kitchens drawing studios, etc. - and use its shape/form language to help you invent a new species of shark.
