12 volts isn't really enough to shock anyone unless it goes through wet skin. The person is likely to be startled (and perhaps slightly stung) by the sparks that fly upon initial contact.

The immediate hazard is from extreme heat as current flows unimpeded through the metal tool. The slightly less immediate but more dangerous hazard is from shrapnel and acid from an exploding battery.
