I have my small backpack with me almost everywhere.
It has the essentials in it. Fire making things, compass, two or more knives between 2" to 4", a huge garbage bag for shelter, whistles and stuff. Since almost all water in lakes and streams in Sweden are drinkable right away you dont need filters and such. I brought a couple of coffee filters to get rid of the worst.
When I am PLANNING on going further than work I add a Fallkniven F1, more lights and a folding saw. The worst thing that can happen here would be a moose coming out in front of your car, then you are toast anyway.
One way to make people accept your idea of preparedness is to add one thing at a time. One day you show up with a multitool in your belt, preferably after someone in the office could have been helped by one, then after a month you a add a light, maybe after a blown fuse etc. In reality you have been prepared all the time but to the locals it appears that you are a bit "too late". So when the screw come loose and the light goes out next time you are prepared and saves the day and everyone will thank you for it. A small Fenix light and a multi tool will probably be accepted everywhere without question. It all depends on the "environment" at the office. After a while they will accept every weird item you carry because they feel secure, not because you carry a MP5 but because they know that if the lights go out you will light the way for them and fix the loose screw on the chair etc.
Then after a month or two or three you become the go-to guy and the questions change from "do you have a gizmo X" to "can I borrow your gizmo X".
The really easiest way is to have everything you might need in your desk drawer or just lying on your desk (not the 4" fixed blade though

) and make the tools surface one by one when the need arise. In the fuse goes you pick up your light and when everyone knows that you have it, you can wear it and so on.
I am the gadget and gizmo guy at work and they even stopped asking politely anymore, they just reach out their hand and say "gizmo X" like a surgeon

One thing is to give people you care about gizmoes for christmas and such. The office girl who is afraid to go down to the basement can get a Fenix L1T or a Surefire G2 and such. A small light or multitool will even fit in the smallest handbag
If you need to bring along a fixed blade dont bring any rambo-delta-swat-death-kill-specops- stealh knives, bring a nice handmade looking 3-4" in a "cuteish" sheath. A nice knife in a nice sheath is usually considered a piece of artwork not a murder-death-kill-thing. If you put your fancy knife on some presentation stand you can still use it but it wanishes in the usual "desk ornament clutter"
