Depends. Two guys who just want to fight are probably going to have a shoving match which will end when one gets pinned and the other guy gets pulled off.
Two groups of guys who have some need to fight over are more likely to use tools.
If two people are having a shoving match, they don't really want to fight. A fight implies you want to hurt the other person, not escalate the situation until one of you gathers the courage to strike the other.
