I have had sooo much "lost" when I have flown. I have put in TSA claim, but that does absolutely nothing. Heck, even my TSA lock was not replaced on the luggage. Things have been torn or spilled. [One trip up North they inspected my checkes luggage and found the TSA approved small jar of cream but didn't put the lid back on. Luckily it was in a zip lock baggie. I just put on the top but used what was in the bag. On the return trip home someone put the cream back in the jar. Too funny!]
So ... can you mail any tools ahead of time to where you are going and have them hold it for you?
When I go up North for my son's wedding I will either get the outfit up there or ship it to my daughter to hold for me.
Obviously I have trust issues with TSA. Different fold interpret things differently and you can't argue with them or you won't fly.
