Can one model be corresponding to multiple collections?

I am working on a tool management small project. In the project, the collections are based on the owner of the tools, and all tools share the same properties like length, description and so on.

Like I create a model of the tools, and create one repo & controller for each collection or how that is going to work.

One page should be corresponding to a controller, and one controller should be corresponding with a repo. Is that correct or there are ways that I can further simplify the model?

All comments are welcomed and I can offer more info if you ask. Thanks again.
