I support the idea of having your own stuff in addition to what office should provide. I hate to depend on office tools which always seems to wander around and not come back without a fight with this or that careless guy

Talking about tool, I would suggest you keep a few basic tools because you never know what kind of improviozation you may need in a survival situation.

Even if you have a multitool, I make sure I have another stand alone pair of pliers. You may need them both to twist / straten a paper clip or whatever. A slip joint pair of pliers is a very useful tool. A multitool typically has a long nose pliers.
