Materials

Over the last two decades, there have been tremendous advances in the material technology used to create hockey sticks. The vast majority of sticks are made with one (or a combination) of the following materials:

Wood

Aluminium

Fiberglass

Graphite (Carbon Fiber)

Kevlar

Titanium

Wood

Wooden sticks are usually constructed by laminating multiple types of wood into a high quality plywood, then coating the stick and blade with thin plastic or fiberglass. Some manufacturers use fiberglass as a laminate between wood layers. Today in the NHL, only a handful of players still use wooden sticks, including Pavol Demitra, Jason Spezza, Paul Stastny and Fredrik Modin.

The main advantage that wooden sticks enjoy today is their relatively low cost. Few wooden sticks cost more than $40 per copy, compared to $200+ for some composite varieties. This makes them a popular choice by younger and amateur players. Wooden sticks also enjoy a reputation of having a good "feel" compared to aluminium or titanium choices. The main disadvantage that wooden sticks suffer from is the relative irregularity and poor durability of the wooden construction. Wood has a tendency to warp, and over time its flex and stiffness properties will change. Additionally, being a natural material, wood also creates variations in production (even between identical patterns), and it cannot be made as "responsive" as certain composite materials (which decreases velocity and accuracy on wrist and snap shots).

It is a common misperception that, for most players, aluminium or composite sticks make for harder slap shots. As it relates to slap shots specifically, wooden sticks have very similar properties to composite sticks, and for most players there will be very little difference in velocity between wood and other materials. It should also be noted that the short list of players with the hardest slap shots in NHL history (Bobby Hull, Al MacInnis, Al Iafrate, among others) all used wooden sticks; however, it must also be noted that these players' careers ended before composite sticks became prevalent (or in the case of Hull, before the advent of aluminium sticks).

Aluminium

Aluminium sticks were the first non-wood sticks to appear. Most aluminium sticks consist of a shaft made of an aluminium alloy and a wooden blade or composite blade, which is held in the shaft by glue and the compression of the shaft itself. There was a time when a majority of NHL players used aluminium sticks, but today around 1% of NHL players use them.

The main advantage aluminium sticks enjoy is their unparalleled durability. It is fairly rare for an aluminium shaft to be broken or damaged, even at the professional level, and since the blades can be easily replaced, a shaft will typically last for a relatively long period of time. Aluminium sticks will not suffer wear or warping like a wooden stick, and they can be manufactured with a great deal of consistency in flex and weight. The biggest disadvantage of aluminium sticks is their heavy or hard "feel", which is a result of the relative hardness of the metal and the imprecise joining of the stick and blade.

Fiberglass

Fiberglass, along with the traditional wood, was the first composite stick material, being added as laminate or coating to wooden sticks. Manufacturers have experimented with 100% fiberglass ice hockey sticks, but they suffered from poor "feel" and poor durability and never really caught on. Currently, there are no 100% fiberglass ice hockey sticks being manufactured (although field hockey sticks are commonly made from pure fiberglass).

Today, fiberglass is most commonly used as a composite with other materials, such as wood, graphite, or kevlar. Generally speaking, a higher density of material was needed in order for the players to perform.

Graphite (Carbon fiber)

Graphite has become by far the most popular building material for sticks used in the NHL, and it is growing rapidly in popularity for amateur and recreational players. Carbon fiber sticks were originally sold as shafts alone, much like their aluminium counterparts. "One piece" sticks, which consist of a single piece shaft and blade, have become the predominant type.

Carbon fiber sticks have become so popular due primarily to the way they combine features of wooden and aluminium sticks. They offer the classic "feel" and performance of the best wooden varieties, and the manufacturing consistency and precision of aluminium sticks. They can also be manufactured with extraordinarily precise "flex patterns" which can aid in the power and accuracy of wrist and snap shots, and their manufacturing process makes it extremely simple to add any number of different materials and features which can dramatically change the properties of the stick (a good example of this being the silicon injections made in certain high-end sticks that are claimed to further enhance their "feel").

Their main disadvantage is their high cost coupled with their relatively poor durability. While their average life is not quite as short as their wooden counterparts, it is poor enough that competitive senior players will usually break one every week or two, which for an entire team over the course of a season can become extremely expensive. This can be a particularly nasty burden for "nonprofit" competitive teams (such as college hockey teams in the United States), some of whom have begun restricting their players from using the most expensive composite sticks.

Kevlar

Kevlar, most commonly known as a bulletproof material, has become a fairly common component of composite sticks. Originally added to increase the durability of aluminium stick blades, it became an ideal addition to the more fragile wooden and carbon fiber sticks, and today it is a material used by nearly every manufacturer. It is a useful component as it dramatically increases the durability of the stick without significantly compromising its weight, feel, or flex properties.

Titanium

Titanium sticks are a fairly new development, and are both extremely rare and extremely expensive. They are usually just a shaft, which will be coupled with a wooden or carbon blade in much the same manner as an aluminium stick. Other sticks have titanium added as a composite material to carbon fiber or kevlar.

Titanium is similar to aluminium in general properties, although it is lighter, stronger, and is said to have notably superior "flex" properties (due mainly to the relative thinness of the walls of the shaft).

Properties

Lie

The lie of a stick refers to the angle between the shaft and the blade. A lie value of 5 corresponds to a 135 angle, and each additional lie value corresponds to a 2 smaller angle. With the bottom of the blade flat on the ice, a higher lie value causes the shaft to stand up straighter. Typical values range from 5 to 7; most sticks now are near 5.5. Goalie sticks typically have a lie between 11 and 15.

Players usually seek a lie that will put the blade flat on the ice while they are in their typical skating stance. Hall of Fame center Wayne Gretzky, for example, used a stick with a low lie to correspond with his deep skating crouch and shorter height, whereas Hall of Fame defenceman Rod Langway used a stick with a very high lie number as he was very tall and tended to skate in a very upright position.

Flex

Hockey stick shafts, much like golf club shafts, are highly flexible, and this flexibility is a key component in their performance. Flex, bend, stiffness, and whip are all terms used to describe the amount force required to bend a given stick shaft a certain amount.

With most composite and alumimum sticks, their flex characteristic is correlated numerically. This number, which ranges from 50 through 120, is printed on the stick and corresponds to the amount force (in pounds-force) that it takes to deflect or bend the shaft one inch. For example, a 100 flex requires 100 pounds force (444 N) to bend the shaft 3 inches.

Stick flex is viewed as a very important characteristic by most players. Commonly, defencemen seek stiffer flex shafts, as their greater stiffness imparts more force on slap shots and improves stick-checking. Forwards will commonly seek more flexible shafts, as they require less force to bend and are thus better suited to create quick and accurate wrist shots, as well as improving passing and stickhandling.

Flex is also correlated to player strength; stronger players will often prefer stiffer flexes, as they have a sufficient amount of strength to fully bend (and thus maximize potential energy) using such shafts, whereas younger players and players with less strength will generally have more success using more flexible shafts which they are capable of bending to their optimal degree.

Blade pattern

Until the early 1960s, hockey stick blades were typically not curved. However, in the late 1950s, New York Rangers center Andy Bathgate began experimenting with "breaking" his stick blades to impart a curve, which he found made his slap shots behave in highly erratic ways. Soon after Chicago Blackhawks forwards Stan Mikita and Bobby Hull stumbled onto the "broken blade", and subsequently began asking their stick manufacturers to create sticks with pre-curved blades.

Soon after, much of the NHL, and Hull in particular, became a proponents of the "banana blade", or stick with extreme amounts (often up to 3 inches) of curve in the blade. These curves made slap shots behave very erratically, and in an era in which goalies did not wear masks, this eventually became an unacceptable danger. By 1967, the NHL began to limit the amount of curve a stick blade could legally have. In the NHL today, the legal limit is 3/4 of an inch.

Much like the shaft's flex, a blade's pattern is a very important characteristic of a stick's performance. There are three primary variables in blade design: curve, face angle, and toe.

The curve refers to the basic amount the blade curves from toe to heel, as well as the part of the blade where that curve is located. A "toe curve" means that the curve is concentrated near the toe of the blade, and it is usually preferred by forwards, who seek better puckhandling and more accurate wrist shots. A "heel curve" is generally better for slap shots, and is thus used more by defencemen.

Face angle is the angle between the ice surface and the front surface of the blade (this characteristic is comparable to the difference between the different irons in golf). A more "open" blade means that the face of the blade is turned up more sharply, and thus will cause a higher trajectory than a "closed" face angle.

The toe shape refers to the basic shape of the end of the blade, and it is typically either round or square. Square toes make it easier to pull a puck off the boards or to do "toe drags" (stickhandling moves using the toe of the blade), whereas round toes make it easier to "flip" the puck, and also offer slight advantages in basic puckhandling.

Blades also differ in length and thickness, based on player preference.

Illegal curves

The curve of a blade is limited at most levels of competitive hockey, generally to an amount between 1/2 and 3/4 of an inch. Hasty measurements can be made by attempting to roll a dime under the blade placed face down on the ice, but accurate measurements require a "stick gauge" which measures curve precisely. Currently, the NHL limits blade curvature to 3/4 of an inch. Being caught using an illegal stick is typically punished with a two minute minor penalty.

The genesis for this rule was the "banana blade" of the 1960s. At the height of this era, players would often simply cross the blue line and let fly with a slap shot, hoping that the bizarre behavior of the puck would beat the goaltender. Goaltenders, who often did not wear masks in this era, were irritated by the danger such wild shots posed to them and in response, the NHL began gradually reducing the amount of curve a blade could legally have.

In the modern game, the emphasis on shooting accuracy has largely eliminated any preference for extreme blade curves. However, hockey still retains illegal stick rules, which has become a cause of debate. The argument is that since blade curvature does not impart any significant advantage, that penalizing it is unnecessary. Additionally, coaches have used the "illegal equipment" penalty at key moments in games to win a power play, and in some cases, swing the momentum of entire series.

Tape

The top of the shaft is most commonly wrapped with cloth tape in a manner which improves the grip on stick by the player's top hand. Most players also apply a "knob" of tape which will create a small gap between the shaft and the ice in the event the stick is dropped, making it easier to pick up the stick. Goaltenders often wrap huge "knobs" on the ends of their sticks (sometimes up to two inches across), which makes it easier for them to poke check without losing the stick (as well as making it easier to pick up a dropped stick).

The blade of the stick is most commonly wrapped with friction tape, a cotton tape that has been impregnated with adhesive so that it is moderately sticky. This is done to improve puckhandling and to avoid water damage to the stick. Some players will also apply wax to the tape in order to increase the adhesion. Preferred amounts of puck adhesion vary among players; some players will use a regular cloth tape instead of friction tape, while Wayne Gretzky used friction tape and then applied baby powder to lower its adhesion. There is also variation in color, black being the most common choice.
