Butter knife (Fallout 3)

The butter knife is a miscellaneous item in Fallout 3 and Fallout: New Vegas.

Characteristics
A butter knife is a silverware item used for spreading various toppings (not only butter) and cutting tender foods. The Pip-Boy 3000 categorizes butter knives as miscellaneous junk.

In Fallout 3 they can be used as ammunition for the Rock-It Launcher, while in the Fallout: New Vegas add-on Honest Hearts they can be used to make scrap metal.
