Methods and Physics of Shooting a Hockey Puck

             Advantages.
             Light weight, stronger than wooden sticks.
             Disadvantage.
             Not as durable as Aluminum hockey stick.
             High price.
             Curvature.
             The hockey stick has to be able to have good puck control and also be lightweight and durable enough to withstand the roughness that hockey has. One of the main features of the hockey stick is the curvature of the stick, when the puck hits the blade the puck is forced to the bottom of the curve. This helps the player have consistent shots because the puck tends to be shot off the same part of the blade. .
             In the NHL, there are regulations on the curvature of the blade. The curve cannot exceed three quarters of an inch. It is measured from a line drawn from the heel of the blade to the end of the blade; the blue line in the diagram below must be no bigger than three quarters of an inch.
             When players curve their blades near the end of the blade it makes it easier to scoop the puck away from another player. But the curves of hockey stick depends on personal preference of that player.
             Blade Pattern.
             The curve of the stick refers to the amount the blade curves from toe to heel and where the curve is located. There are three variables in curve design: curve face angle and toe.
             A toe curve means the curve is located near the toe of the stick. Forwards prefer this curve for better stick handling and accurate wrist shots.
             The heel curve is generally better for slap shots so it is used more by defensemen. The end of the blade is called the toe and it normally comes into two different shapes, a round toe which makes it easier to flip the puck and slight advantage in basic stick handling.
             These are some examples of the different types of curves:.
             Loft/Lie.
             The "loft"" and "face"" of the blade is another feature that affects the control of the puck. This is the tilt angle of the blade; you can see it when you're looking at the stick from above. Just like in the picture below. The bigger the tilt, the easier the puck will lift up and get airborne.
