ARROW STRAIGHTNESS AND THE ± 0.0$ FACTOR

Most carbon arrows are advertised to have a specific straightness tolerance between .001" and .006". The straighter the arrow, the more expensive they will typically be. Before we get too deep into this topic, it's worth noting that there doesn't seem to be an accepted universal method for HOW arrow straightness is measured. Per ATA/ASTM standards, arrow straightness should be measured along the full length of the shaft minus two inches. But as we understand it, this is NOT how things actually go inside the industry. On a number of occasions, we have heard arrow companies accuse each other of cheating their straightness measurements - either by measuring only short sections of their arrows, or by obtaining their straightness numbers via undisclosed measurement methodologies. If you think the bow business is cut-throat, you should witness how the arrow companies go at it behind closed doors. To avoid being shanked at the next trade show, we'll stay neutral, and assume that everyones' arrow straightness numbers are reasonably honest and comparable.
With that said, let's examine the typical straightness "classes" of arrows. Most standard-grade carbon arrows have an advertised straightness of .005-.006". These shafts are usually marketed exclusively to the hunter and beginning archers. For the purposes of big game hunting and general target use, standard-grade shafts are more than adequate. A typical human hair is about .004"-.006" in diameter. So even a basic carbon shaft of .006" straightness is quite good, and straighter than you could possibly perceive without specialized equipment.

But ... making and selling arrows is a very competitive business. So most arrow shaft manufacturers also offer a mid-grade shafts which will have an advertised straightness of around .003-.004", and "pro" grade shafts claiming a straightness of .001-.002". And as you might expect, these premium grade arrows fetch a premium price. If you're the kind of buyer who always goes for the good stuff, then by all means, buy the straightest shaft you can find. But before you shell out the green for a ±.001 shaft, there are couple things you should know.

Rolled Up CarbonFirst, the difference in a ±.006" shaft and a ±.001" shaft is more razor-thin than you might think. Carbon arrow shafts are constructed by taking very thin layers of carbon sheets and rolling them up into perfectly straight tubes (usually 6ft. long or so), much like you might roll-up a big map. Once wound, the carbon tubes are then heat-treated to bond all the layers together. When the heating process is complete and the carbon tubes cool down to room temperature, they are cut into sections (raw shafts). Some of the shafts, particularly those that come from the center of the roll, retain their ±.001" straightness while other sections distort slightly from the heating/cooling process.

As we understand it, the results vary from run to run and day to day. In most cases, even the manufacturer doesn't know how the day's crop of shafts will come out. But once the shafts are made, the manufacturer measures the straightness of each shaft and sorts them accordingly for banding and sale. One sort may be named and marketed as one arrow, another sort as something else. For example, the Beman Bowhunter ±.006" @ $64.95 p/dz and the Beman ICS Hunter ±.003" @ $89.95 are just two different sorts of the same shaft - same raw materials - same construction technique. Same is true for the popular Gold Tip Expedition ±.006", Gold Tip XT ±.003", and the Gold Tip Pro ±.001". They're literally cut from the same cloth.

Small variations in the daily manufacturing environment (humidity, pressure, air convection patterns, etc.) along with tiny deviations in the characteristics of the raw materials ultimately determines the straightness of the finished product. On one particular day, the manufacturer might yield an entire batch of ±.001" shafts, or an entire batch no better than ±.006", or even a mixed bag of straightnesses, all from the very same processes and materials. The finer tricks of the trade are carefully guarded secrets, as the art of consistently building straighter arrow shafts is literally a technical exercise in splitting hairs. But make no mistake, arrow manufacturers would rather avoid the ±.006" days. The more ±.001" days a manufacturer has, the more money they can make. Why? Because straighter shafts, whether they cost more to manufacture or not, are worth more in the marketplace. So don't be fooled into thinking that your set of $129 ±.001" pro-grade shafts are somehow fundamentally better constructed, stronger, or made from finer materials than a basic $69 a dozen ±.006" hunting shaft. In most cases, they're just a few thousandths of an inch from being the exact same product.
