Final answer:
A crosscut handsaw is used to cut against the grain of the wood, designed with teeth that facilitate cross-grain cutting without causing splinters.
Step-by-step explanation:
The type of handsaw that cuts against the grain of the wood is known as a crosscut saw. This saw is specially designed with teeth that are shaped to cut across the wood fibers rather than along them, which is the case with a rip saw. The crosscut saw makes it easier to cut wood across the grain without tearing or splintering the material. In the context of lumber production, a two-person crosscut saw can be used, which allows for efficient cutting through large logs due to the combined effort of two individuals.
