You either shake the Wii remote (there are options to turn this on or off) or press the down d-pad button. It is very useful and I get a few kills each match shanking people. I usually just spam the down d-pad button. Sometimes the knife fights last awhile with both people getting confused where the other person is and sometimes end with someone backing away and unloading a clip into them.
