- Knife becomes knives.
- Leaf becomes leaves.
- Chief becomes chiefs.
- Cliff becomes cliffs.
- Scarf becomes scarfs or scarves.
- Dwarf becomes dwarfs or dwarves.
Of note, some dictionaries may list rooves as a secondary spelling, but it is an archaic form of the plural and almost never used in modern-day writing. (See the evidence in Google's Ngram Viewer.)
