Besides a magnet...what are other essential tools every scrapper should have?

This question has probably been asked as many times as: "Is it worth it?". What kind of tools do I use?, my brains and cold beers would be at the top of my list, but that list is a never ending list. Patriots reply had me doing a little thought on how many cell phones have I had? I know I have never lost one, but I have had one since the late 80's. The first one is in a box somewhere I know, always getting a new one one when there is nothing wrong with the old one, what does that say about me? I know I'm not the only one doing that!

On the other hand I have worn the same multi-tool on my belt since the late 80's too! Mine is not a Leatherman, but a Gerber with the sliding safety lock pliers. Both the Gerber and the Leatherman are made in Portland, Oregon (different companies). If my Gerber was to get lost or it breaks, maybe I'll try a Leatherman. The one thing I'm certain of, I will have another cell phone before that happens!
