How do I deduct my hand tools for my real estate practice and client party?

Two in one question. I am a real estate broker and I manage properties. In the process I have to do repairs on certain properties and have purchased hand tools for this purchase. I don’t want to have to capitalize and all that for a 3.99 screwdriver so how do I deduct these purchases.

Part two. If I throw a client party at my house, can I write off the entire amount or is it subject to the 50% entertainment stuff.

Thanks in advance for your answer.
I have several hand tools so the screwdriver is an example. I can’t imagine I have to fill out a sect 179 deduction for each one
