Riving(rive) means tearing or splitting in Norwegian and English. The word comes from Old Norse and is commonly used in Norwegian, but I didn't know it also was an english word.

To me "I couldn't open it, so I had to rive it." sounds like Petter Solberg(known to mix norwegian and english) trying to speak english. "It's not the fart that kills, it's the smell" (fart meaning speed in norwegian, and smell meaning crash)
