The sledgehammer is a tool used to "fix" dents on Satsuma. It can be found in the garage at home, leaning against the wall next to the table. Other applications for the sledgehammer include, but are not limited to:
- Whacking your neighbours
- Breaking down barn doors (to get cars to Fleetari)
- "Cleaning" Teimo's Shop windows (to steal fuel)
- "Fixing" other people's cars.
