Difficulty: Easy
Correct Answer: is used for cutting along the grains of wood
Explanation:
Introduction / Context:
Hand saws are specialised for different cutting directions relative to wood grain. Selecting the correct saw improves surface finish, reduces effort, and prevents tearing of fibres.
Given Data / Assumptions:
Concept / Approach:
A rip saw is designed for cutting parallel to the wood grain (ripping). Its teeth are shaped like small chisels with a relatively large rake angle to sever fibres along their length. Crosscut saws, conversely, have knife-like teeth set to sever fibres across the grain. Two-man saws are typically crosscut types for felling logs, not rip saws.
Step-by-Step Solution:
Identify direction of intended cut: along fibres.Match tool: rip saw with chisel-tooth geometry for ripping.Reject two-man saw description and narrow-blade twin-handle (keyhole) descriptions.Select the statement that correctly defines a rip saw.
Verification / Alternative check:
Examine tooth geometry charts: rip saw teeth are filed straight across, suited to longitudinal cuts.
Why Other Options Are Wrong:
Two-man saw: used mainly for crosscutting logs.Narrow blade with two handles: describes keyhole/compass saws, not rip saws.Across-the-grain only: that is crosscut saw usage, not rip saw.
Common Pitfalls:
Using a crosscut saw to rip leads to wandering cuts and rough surfaces.
Final Answer:
is used for cutting along the grains of wood
