The knives in my car are more for emergency use.
I had a Leatherman Wave in there, but it's now in my EDC pack because I commute on weekdays. When get around to buying a Vic SwissSpiritX, back in the car it will go :thumbup: I have a Spyderco Delica in the glove compartment also.
I carry a Fallkniven F1, and a Mora as part of the car emergency kit (and also used for impromptu hikes). In addition, I have a Becker BK9 on the way that might live in the car for emergency use and camp beater (when not on hiking trips) :thumbup:. Also, I have a pocket chainsaw in the car emergency kit; came across a downed tree on a remote road a while ago, had to backtrack. Might have been able to continue if I had the saw.
