Choose the word which is different from the rest.

The answer is B. Axe.

An axe is a tool or weapon with a long handle and a heavy blade, typically used for chopping wood. A knife is a tool or weapon with a sharp blade, typically used for cutting or stabbing. A dagger is a short, pointed knife, typically used for stabbing. A sword is a long, sharp-edged weapon with a hilt and a blade, typically used for cutting or thrusting.

An axe is different from the other options because it is the only tool that is not primarily used for cutting or stabbing. An axe is primarily used for chopping wood.
