This is just my personal experience, but I have never seen a knife or multi-tool that had a wire cutter on it that was robust enough to actually cut wire without doing damage to the tool. Unless of course it was so big and heavy as to be impractical for what I consider every day carry. The AK-47 bayonets are pretty good, but much heavier than the type of knife I would typically carry for every day use. YMMV
