knife

In your front yard, the weeds are highlighted by the moon such that you can cut them with your knife.

If you return someone to dust with your knife, you better clean up with your broom.

You smell decay and feel a knife at your throat. You're in death row.

Upon arrival to a dangerous place, you always arrive with a knife.

To separate your mouth from danger, you wrap your knife.

A shellfish with a knife rules this place.
