How composite sticks changed the slap shot

HostIf you look at an old hockey game from the fifties or sixties, the sticks look like something you would find in a wood shop. Just flat, heavy pieces of ash or elm. But today, players use these sleek, hollow tools that look more like space gear than sports equipment. I was watching a game last night and noticed how much the sticks bend when someone takes a big shot. It almost looks like the stick is made of rubber. How did we get from those heavy wooden planks to these high-tech sticks that seem to do all the work?

GuestIt was a slow change that turned into a full-blown shift in how the game is played. For a long time, wood was all we had. It was cheap and tough, but it was heavy. If you wanted a stiff stick, it had to be thick. Then in the nineties, things started to move. First, we saw aluminum shafts with wood blades glued into the bottom. But the real jump happened when companies started using carbon fiber. Think of carbon fiber as thousands of tiny, super-strong threads all woven together like a shirt and then soaked in a hard glue. This let engineers build a stick that was light as a feather but could hold a massive amount of weight without snapping. The big thing it changed wasn't just the weight, though. It was how the stick acts like a spring. When a player takes a slap shot now, they aren't just hitting the puck. They're actually using the ice to bend the stick into a bow shape before they even touch the puck.

HostThat sounds like it would actually slow you down. If I'm trying to hit something hard, hitting the ground first usually just hurts my wrists and kills my speed. Why would you want to hit the ice before the puck?

GuestIt feels wrong because we think of a hockey stick like a baseball bat or a golf club. With a bat, you want a direct hit to move all that power from your arms into the ball. But a modern hockey stick is a different beast. When the player swings, they aim to hit the ice about an inch or two behind the puck. Because the stick is made of these layers of carbon, it doesn't just stop. It bows. The middle of the stick bends way back while the top and bottom stay firm. For a split second, that stick is holding all the power of a two-hundred-pound athlete leaning their entire body weight into it. It’s like pulling back the string on a bow. When the stick finally moves past the ice and hits the puck, it snaps back into its straight shape. That snap adds a huge burst of speed that your arms alone could never create.

HostSo the player is basically loading a spring and then letting it go. But players are so much stronger now. Is the stick really doing that much, or are we just seeing better athletes who know how to use the gear?

GuestThe athletes are definitely in better shape, but the gear has raised the ceiling of what's possible. In the old days, a hard shot was maybe eighty miles an hour. Now, guys are hitting over a hundred regularly. And here is the catch. With a wood stick, every single one was a bit different because wood is a natural thing. One might have a tiny knot here or a soft spot there. You never knew exactly how it would bend. With these new mixed-material sticks, they're made in molds. They're the same every single time. Engineers can even choose where the stick bends. They call it the kick point. Some sticks are built to bend near the bottom for a quick snap, and some bend in the middle for those huge slap shots. It has turned the shot into a science. You pick the tool that matches how you play.

HostI see players break these things all the time, though. It seems like every game someone tries a big shot and ends up holding a useless stub while the puck just sits there. If these materials are so great, why do they snap like twigs?

GuestThat's the trade-off. To make them so light and springy, they have to be thin. Carbon fiber is incredibly strong when you pull it or bend it the way it was meant to go. But it's also very brittle. If a stick gets a tiny crack from another player’s skate or a different hit, it loses its strength. Then, when the player tries to put all that weight on it for a slap shot, the whole thing just gives up. Wood sticks would mostly just splinter or get soft over time. These new ones are either perfect or they're in two pieces. It's the price you pay for that extra ten miles an hour on your shot.

HostIt must be a nightmare for the goalies. If the puck is coming in that much faster and the players can get the shot off with less of a wind-up, how do they even see it?

GuestThey almost can't. It has changed the way goalies play the game. Back when shots were slower, a goalie could watch the puck the whole way and react to it. Now, because the release is so fast and the speed is so high, a lot of it's just about being in the right spot before the shot even happens. They have to play the odds. They use bigger pads and try to block as much of the net as they can because if a pro player gets a clean look with a modern stick, the puck is in the net before the goalie can even blink. The puck has become a blur.

HostThe goalie is basically playing a game of catch with a cannonball.

GuestA cannonball that can change direction. Because these sticks are so consistent, players have learned to use that flex to hide where they're aiming. They can lean one way and snap the puck the other way using just the tip of the blade. It has turned the slap shot from a slow, heavy move into a lightning strike that can happen from anywhere on the ice.

HostThose thin threads of carbon turned a simple wooden tool into a high-speed launcher that changed the whole pace of the game.

GuestThe sport has basically become a race between how fast a human can move and how much energy a thin tube of carbon can hold before it gives up.

HostThat heavy wood plank from the old days seems like a different tool entirely now that we see the modern stick as a loaded spring waiting to snap.
