🔍 Key Concepts

• How different tooth sets on hacksaw blades control the direction and width of the cut (kerf) • The meaning of terms like alternate, double alternate/raker, and wave sets in metal-cutting saws • How the pattern "two right, two left" differs from a simple one-right/one-left pattern

💭 Think About

• Visualize or sketch what a simple alternate set (right, left, right, left, ...) would look like, and compare it to "two to the right, then two to the left". • Ask yourself which term is normally used in tool manuals for a repeating pattern of multiple teeth bent one way, then multiple teeth the other way. • Think about which option names are commonly used to describe more complex or grouped tooth patterns beyond simple alternation.

✅ Before You Answer

• Be clear on the difference between single alternate (every other tooth) and patterns that group teeth together. • Recall which term is associated with a group or cluster of teeth acting together, rather than each tooth alternating individually. • Eliminate any option that clearly refers to a curved or wavy tooth line rather than discrete right/left staggering.
