Well I planned to get to work, but had parked my old bmw on thick ice. Backwheels spinned, car didnt move an inch. Tried to push, but I couldnt get enough grip with my feet because I also stood on ice. Put the floor mats under the back wheels (like I learned on Tv) and found them somewhere in front of the car again. So I did it the manly way. I opened up my kershaw and started to stab into the ice right behind the back wheels. Was kind of afraid to hit a tire, but didnt and got out of there without a problem. I love knifes - perfect tool.
