Final answer:
A crosscut blade would be recommended to cut wood perpendicular to its grain.
Step-by-step explanation:
If a length of wood had to be cut perpendicular to its grain, a crosscut blade would be recommended. A crosscut blade is designed with many small, sharp teeth that are oriented at a 90-degree angle to the blade. This type of blade is specifically made for making cuts across the wood grain, resulting in clean and smooth cuts.
