Of course tool matters. It is harder to kill with a stone or a rock or a knife than a gun. Death rate is high with a gun than with other things. A rock is a rock, but you have automatic pistols, machine guns, shot-guns and so on which can give a sure death. There is a good chance in some cases you can defend yourself against a knife or rock and in some cases you can out run the other guy and escape. You see my dear friend it is the tool.
