Hockey stick
In ice hockey, the end or blade of the stick is normally curved, to help the player get better control of the puck and better shots at the goaltender.  The goaltender has a bigger blade, to make it easier to stop shots.  Players sometimes use hockey sticks to hold back the bodies of other players, or to trip or hit them; sometimes players who do this get penalties. In field hockey, sticks are shorter, but the blade is thicker, than in ice hockey.  It is used to move a ball instead of a puck. More research has gone into studying how hockey sticks perform. The main difference between the two sticks is how they are used in the games.
