Complete sledge hammer ban.
Require a license for every hammer owned, and the license is only given when someone reaches 18, after psychological testing by a doctor, and showing expert knowledge how to use it.
The license should be renewed every 2 years, and only one renewal is required for all licences possessed.
If a person with a license commits a crime with a hammer, the doctor that gave the test should have their right to issue the licenses revoked.
People who are convicted felons, have a history of mental disorder or drug or alcohol addiction are banned from owning hammers.
Owning a hammer without the proper license is a felony with automatic prison time.
Have a damn good reason for leaving the house with a hammer.
