Which of the following is a common type of hammer?

• A. Ball-peen
• B. Screwdriver
• C. Wrench
• D. Chisel

Answer: (A)

Recognizing common hammer types and their uses helps you choose the right tool for metalworking tasks. A ball-peen hammer is a standard hammer with a flat striking face on one side and a rounded peen on the other. The flat face delivers a clean, controlled strike, while the rounded end is ideal for peening (hitting and shaping metal), rounding off edges, and driving punches or chisels without marring the surface. This combination makes it a staple in many shops.

The other tools listed aren’t hammers at all. A screwdriver is for turning screws; a wrench is for tightening or loosening bolts and nuts; a chisel is used to cut or chip away material. So the ball-peen hammer is the one that fits the hammer category.
