🔍 Key Concepts

• How hand tools, especially hammers, are commonly specified in catalogs and on tool markings • Which part of a ball peen hammer most directly affects how hard it can strike • Difference between physical dimensions (length, diameter) and functional rating (like force or striking capacity)

💭 Think About

• When you buy or order a ball peen hammer, what information is usually printed on the hammer or listed in the catalog? • Which part of the hammer changes the impact energy the most: the length, the face diameter, the peen size, or how heavy the striking end is? • Think about other hammers you know (like claw hammers or sledgehammers). How are those usually described in terms of size?

✅ Before You Answer

• Focus on how impact tools are labeled: is it by a physical measurement or by something related to mass? • Ask yourself which feature would be most important to control striking force and suitability for the job • Eliminate any option that seems more like a convenient dimension than a standard industry sizing convention
