I always have a knife on me, other than that it's a little difficult to carry much as I wear a suit for work and...Well, it's just not always possible.

I have a go bag in each of my cars though, with all the goodies including a first aid kit. I also have a seat belt cutter and glass breaker in all my cars.

I've got a thing I carry around with a cut-down version of my vehicle go-bags also. It's like a bandolier but the pouches are a little bigger, sort of like medical pouches a Corpsman may carry. It looks ok and has a lot of kit. I keep that in my big-dog (Toyota Landcruiser) as it comes in handy if I want to go for a sneaky hike or invade a neighbouring country. I'm a prepper so, I'm prepared for stuff.

I love that knife mate!
