Count from a text list, excluding duplicates, with multiple criteria

Hello,

I know this has been asked a lot, but I'm not finding anything that seems to work in my case.

In the attached example, I am trying to count the total number of unique tools. I would only like to count the rows where columns A and B match. Then for the unique tools only, I want to count the totals of each status from column C. I want to do this with a formula because this is a shared workbook and I can't use tables. Right now I have the total counts in the table on the right, but it is not excluding duplicates. If someone could help it would be greatly appreciated.
