Which statement is true about hammers?

• A. Make sure the head is fitted correctly to the shaft.
• B. Use a hammer with a defective shaft.
• C. Always swing with the hammer by the head.
• D. Keep the head loosely attached.

Answer: (A)

The key idea is safety and proper tool integrity: the hammer head must be securely fitted to the handle. When the head is properly fitted, the impact energy stays with the head and shaft as a single unit, so it won’t loosen or fly off during striking. A defective shaft or loose fit compromises control and can cause serious injury or damage. The other statements describe unsafe practices—using a hammer with a defective shaft or keeping the head loosely attached increases the risk of the head detaching or losing control. Also, you don’t swing by the head; you grip the handle and strike with the hammer’s face to maintain control and accuracy.
