Question:
Cutting and Y shaped teeth are found in ________ cross cut saw for felling of trees and conversion into logs.
Cutting and Y shaped teeth are found in ________ cross cut saw for felling of trees and conversion into logs.
Show Hint
Raker teeth act like little chisels or rakes; they are easily recognized by their distinct Y-shape or deep gullets designed to clear sawdust out of the cut.

The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
Logging and tree-felling hand saws are designed with specific tooth patterns to maximize cutting efficiency and clear sawdust from the cut channel (kerf) when processing large green timber logs.
Step 2: Detailed Explanation:
- In cross-cut saws, different tooth shapes perform different tasks.
- Rakertoothing consists of a repeating pattern of cutter teeth and raker teeth. The cutter teeth (usually triangular) cut the wood fibers, while the specialized Y-shaped (or straight-ended) raker teeth follow behind to scoop up and clear the loose sawdust from the cut.
This prevents the saw from binding or clogging, which is essential when cutting dense or wet green wood.
- Peg toothing consists only of triangular cutting teeth without rakers, making it less efficient for clearing wet sawdust.
- Pickroons and cant-hooks are handling tools used to roll or lift logs, not saw teeth.
Step 3: Final Answer:
Cutting and Y-shaped teeth are characteristic of rakertoothing in cross-cut saws.
