Detailed Explanation:
To determine the word that is different from the rest, we need to look for a characteristic or feature that distinguishes it from the others. Let's analyze each option:

1. Axe: An axe is a tool with a sharp blade that is used for chopping wood. It is commonly used in activities such as forestry and construction.

2. Knife: A knife is a cutting tool with a sharp blade that is used for various purposes such as cutting, slicing, or stabbing. It is commonly used in cooking, hunting, and other activities.

3. Shovel: A shovel is a tool with a broad blade and a long handle that is used for digging and moving loose materials such as soil, sand, or snow. It is commonly used in gardening, construction, and clearing pathways.

4. Saw: A saw is a cutting tool with a toothed blade that is used for cutting through materials such as wood or metal. It is commonly used in carpentry, woodworking, and other activities.

By comparing these options, we can see that the word "Shovel" is different from the rest because it is the only tool that is used for digging and moving loose materials. The other three options, Axe, Knife, and Saw, are all cutting tools used for different purposes.

Therefore, the correct answer is option 'C', Shovel.
