🔍 Key Concepts

• Common hand tool terminology for cutting edges and blades • Difference between tooth spacing and tooth angle on a saw blade • How we normally describe how “fine” or “coarse” a hacksaw blade is

💭 Think About

• Ask yourself: when you choose a hacksaw blade for thin metal vs thick metal, what specific measurement are you looking at on the package? • Which of these terms is used to describe the spacing/number of teeth along a length of blade, rather than the angle or side bend of the teeth? • Eliminate any options that usually apply to screws/bolts or to how teeth are bent, not how many teeth there are per inch.

✅ Before You Answer

• Identify which option refers to teeth per inch (TPI) or spacing between teeth. • Separate terms that refer to tooth angle or cutting edge shape rather than spacing/count. • Notice if any choice is primarily used for thread measurement on bolts and pipes, not saw blades.
