Tell me please if I need to include the definite article in the following sentence.
I cannot fix the computer right now as I don't have (the) necessary tools for it.
I am not sure whether to use it or not because on one hand I didn't specify what tools was needed, therefore the article isn't necessary. But on the other hand it is clear what tools was needed. The ones which fit for fixing the computer, and so the article seems to be necessary. Could the use of it be optinal?
