Hockey Sticks - A Background

Hockey sticks have come a long way over the years. At one point they were all made of wood and did not even have a curve. now sticks are made with curves for both left and right handers in a variety of patterns, flexes, etc. Follwing is a back ground of the types of hockey sticks.

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.

The main advantage that wooden sticks enjoy today is their relatively low cost and strong base. 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. 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).

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 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 two 100% fiberglass sticks on the market which are made by Warrior.

Today, fiberglass is most commonly used as a composite with other materials, such as wood, graphite, or kevlar.

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.

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.
