So he is teaching the MC how to use small sized weapons,medium sized weapons,long weapons, and ranged weapons which applies to much more weapon types than just a sword,daggers,spear,and a bow and arrow. It is interesting and I wonder how the MC's class uses weapons to the point where he needs to be decently competent in at least 4 of them which with the hot fix will be 5 if you count hand to hand combat..
