Company supplies specialty items and all PPE, I supply everything else. There are things like meters, leak detectors, vacuum gauges, and certain wrenches that they will provide, but I choose to use my own stuff. If anything I am using breaks on the job, no matter who it belongs to, they'll replace it with no questions asked. I would rather buy high quality stuff of my choosing than have to use whatever is in the shop or whatever their preferred supplier carries.
Don't pick the fly crap out of the pepper.
