Last I went (about 4 years ago), they did a quick check of your backpack, they never questioned my leatherman that was in it, and just moved it aside to check further. Disclaimer here - at the time I worked for a company owned by Disney, and was entering on my employee vacation pass (NOT my work ID, but it's fairly obvious you are a 'fellow cast member' with his family) - never said a word to me, and even gave me a couple of quick tips for the day
