The method for replacing the blade in a changeable-razor will vary depending on the ____________.

Model
Manufacturer
Design
Type

The correct answer is: Model

The correct answer is based on the idea that different models of changeable-razors can have distinct mechanisms or methods for blade replacement. Each model may include variations in design features, safety protocols, or specific instructions that reflect its unique construction. Models might include differences such as how the blade locks into place, whether it requires a certain tool for replacement, or even the way the blade is secured within the razor body. While the manufacturer, design, and type are relevant factors, they can often encompass a wider range of products than just a single model. For instance, multiple models can exist under the same manufacturer, each with their own blade replacement method. Therefore, it is the model that most directly influences the specific procedure to replace the blade in a changeable-razor. Understanding this distinction helps ensure safe and effective blade changes, which is crucial for both the user's experience and the integrity of the shaving tool.
