Alien Haresting Knife
The assignment was to design some kind of artefact matching a given fictive world.
"This knife was found on a earth-like planet far far away.
It is used by the planet’s inhabitants for the harvesting of some kind of nutritious orange claw-like nut.
The tripod aliens calls this nut something that translated means fire-seed.
This relates to the very high flammability of the contained oil and the planet’s fire season.
The knife has a handle that is used by twisting the tentacle-arms around it.
Inside the knife is a twig with fire-seeds to ensure survival of the species."
