e21 SCANDIUM SC GOLF SHAFT GEOMETRY
It's the ONLY shaft in the world that reacts the same way for every degree out of 360 degree revolution on its axis. 99.9% Symmetry is the answer compared to steel at 85% and graphite 67% symmetry.
All e21Scandium Golf shafts are approved by USGA and despite their amazing performance adhere to ALL the rules.
Scandium, is very fine grained and consistent at the molecular level. Scandium is much more consistent than traditional alloys, which accounts for its high strength to weight ratio.
Scandium technology requires unique know-how that is not generally available. As it's very difficult to make a 25-step secret seamless process from a single piece of metal resulting in unmatched consistency. Similarly, steel shafts are welded, creating a seam or spine invisible to the naked eye. This difference in tube wall thickness at the weld point creates an imbalance that requires pureing. Scandium does not require this time consuming process.
Scandium shafts also have the industry's best torque ratings, as low as .5 torque at playing length measured in degrees. This is the twisting movement of the shaft during impact, the more torque a shaft has, the more the club head will twist at impact causing inaccuracy.
Scandium has a 70% higher strength to weight ratio over steel allowing for extremely lighter shaft weights and a thicker than standard wall thickness. This not only creates low torque but this distinctive property also prevents “ovaling” a phenomenon challenging golf shaft engineers to this day. Unlike torque which is the ability to resist twisting, ovaling is the result from a linear applied downforce on a golf shaft tube which leads to the bending or collapsing of a normally symmetrical round tube to a football “oval” appearance. This can be seen on slow motion
video from behind of the golf shaft sagging and the club head drooping on the downswing.
This feature along with the low Torque of Scandium shafts increases your chance by 2300% of getting a hole-in-one. And this is no guess...This was calculated by a Ph.D in mathematics that did this analysis. Due to the fact that the accuracy of each shot is greater, each shot decreases the avg. square where there's a probability that the ball will land. Normally that is 10ft. x 10ft. square, Scandium shafts reduce that square to 3ft. x 3ft.
Finally Scandium shafts have 2 different ways to deflect vibration called SHOCKBLOK. The first is do to its molecular properties, its tensile material is softer than steel. This prevents it from oscillating or vibrating. The second is its variable wall thickness, the shaft thickness decreases in stages using wave guide principles, just below the kick point of the shaft is an energy reflection zone that sends the reflected energy back towards the club head and ball.
Every year over 1700 innovations are produced in golf. Out of these, only 50 make it through a US patent office. That is every year for the last 20 years. So out of 34,000 inventions and technologies in the last 20 years. Scandium is the very first new material invention in golf since Titanium was introduced 34,000 inventions ago! Out of these inventions, Scandium is the ONLY patented invention with its own place on the Periodic table of Elements, and only the 7th material with this title in the entire history of golf technology and inventions.

SCANDIUM SC GOLF SHAFT GEOMETRY
Tip trimming related to constant weight taper tip.
1.Scandium shafts were not made to be unitized (same blank starting weight for every shaft) if they were they have only 1 gram weight for the entire set. Example of this is like True Temper unitized (parallel tip) shafts that have a blank weight of 127g for the entire set but after tipping and butt cutting the shaft becomes lighter as you move from the 3-Iron to the PW or also called a descending weight set. 123g weight on the 3-Iron 104g weight on the PW. This is not preferred by Tour players or Original Equipment Manufacturer (OEM’s), the preferred setup is a constant weight (tapper tip) shaft that is the same weight on a 3-Iron (127g) and (127g)
on the PW. To accomplish this, a machine has to start with different wall thickness and gram weights for
each shaft since the finished length of each shaft is shorter than the previous shaft. To maintain the same
flex throughout the set, the tip section is longer on the 3-Iron and shortest on the PW. No tip trimming can be
done by the club builder or the OEM after this process. One option is to step it up (3 Iron shaft into a 4 Iron)
and make it weaker, or to step it down (4 Iron shaft into a 3 Iron) and make it stiffer.
2.Scandium shafts are available in 42 inch blanks starting at 80g and moving in 1 gram increments up to 150 grams along with an increase in wall thickness. The tip section is a constant parallel length of 5 inches and the butt section is a constant parallel length of 19 inches no matter what the gram weight. This was done to allow club builders or an OEM to make a constant weight set by moving in 1-3 gram increments per shaft blank.This allows for different playing weights & swingweights due to variable OEM’s head weights. Scandium for the first time in history we can have the same shaft used in either parallel hosel heads or a tapper tip heads. This can only be done because of the unique features of Scandium by lightly belt sanding the outside diameter of the tip after trimming or by using an end finisher in our OEM factory.
3.Our lightest playing weight set at this time is 80 grams by starting with an 90g blank shaft in a 3-Iron and move in 1g increments to 88g in the PW. The heaviest playing weight set is 118 grams by starting with a 130g shaft blank in the 3-Iron an move in 3g increments to a 151g blank in the PW.
4.We need to demonstrate some basic math equations for fitting Scandium golf shafts when it comes to
maintaining constant weight compared to playing length. Take a 42” blank that weighs 80g and divide it by
its length of 42 inches. 80 divided by 42 = 1.90g per inch or 1g per 1/2 inch. 117g divided by 42 = 2.78g per
inch or 1.4g per 1/2 inch. 130g divided by 42 = 3.09 per inch or 1.55g per 1/2 inch. Almost all low handicap
players like a constant weight or an ascending weight set where the PW shaft is the same or heavier than
the previous shaft. This is why we move in 1g increments on the lightest shafts 2g on or middle weights and
3g on the heaviest shafts. Now we need to look at the playing length of the shaft. A typical 3-Iron shaft with
a hosel length of 2 inches a tip insertion of 1 inch is 38 inches. 4I-37.5” 5I-37” 6I-36.5” 7I-36” 8I-35.5”
9I-35” PW-34.5”. So we remove -4 inches from a 42 inch blank on a 3-Iron. (4I -4.5”) (5I -5”) (6I-5.5”) (7I -6”) (8I -6.5”) (9I -7”) (PW -7.5”).
5.A Scandium shaft is in perfect balance from the butt to the tip. A half inch butt section weighs the same as
a half inch tip section. So if I have a 117g blank on a 6-Iron tipped 1/2” I will be removing 5” from the butt for
a total 5.5 inches. 117g divided by 42=2.79g per inch x 5.5 = 15.35 117g -15.35= 101g playing weight. So to
make a set 100g playing weight I would need to use the following raw gram weights. (111g 3I) (113g 4I)
(115g 5I) (117g 6I) (119g 7I) (121g 8I) (123g 9I) (125g PW). Also remember when we tapper the tip we
lose .75g in weight.
6.Scandium shafts have a proprietary 25-step process resulting in 99.9% perfectly symmetrical tube compared to 85% in steel shafts. Extruding a shaft instead of rolling and welding creates no seams so “puring” is not required.
7.A Scandium shaft has a 17” parallel butt section before the first visible step and unlike steel shafts one of the fundamental unique features of Scandium is that it has a butt soft not a butt stiff section. This plays an extremely important feature in fitting because unlike steel shafts the longer the butt section the softer the flex (higher the ball flight) of the shaft, NOT STIFFER. This is very important when flighting and tipping the shaft or going longer or shorter than standard length clubs.
8.A Scandium shaft has a very short 5” parallel tip stiff section before a visible step followed by three invisible
patent protected steps. These three invisible steps play a major role on the very stable bend section of the
shaft which is shown through an independent crush test, over a 4” surface area 12”-16” from the tip. This
high bend point or flex point over this large surface area gives Scandium the ability to fit a larger variance in
swing speeds as opposed to conventional steel shafts. This high bend point along with the soft properties of
Scandium gives the soft feel and the most desirable launch angle of any shaft today even with the incredible
low torque rating of 1.4. Low torque shafts have been long associated with a heavy weight and harsh feel.
9. Scandium has a 70% higher strength to weight ratio over steel allowing for extremely lighter shaft weights
and a thicker than standard wall thickness. This not only creates low torque but this distinctive property also
prevents “ovaling” a phenomenon challenging golf shaft engineers to this day. Unlike torque which is the
ability to resist twisting, ovaling is the result from a linear applied downforce on a golf shaft tube which leads
to the bending or collapsing of a normally symmetrical round tube to a football “oval” appearance. This can
be seen on slow motion video from behind of the golf shaft sagging and the club head drooping on the
downswing. This feature is one of the most significant of Scandium shaft fitting. The most important
feature of a golf shaft is to create optimal launch angel or bending in the swing plane (the flex or loft of the
club) optimal distance and the tightest shot dispersion towards a given target for a given swing speed. If a
standard steel or graphite shaft is fit to a too weak of flex the ball will go left of the target line and too high,
too stiff a flex the ball will go right of the target line too low and results in a loss of distance. Because of all
the distinctive properties of Scandium shafts, a too weak of a shaft flex the ball will go too high but it will not
leave the target line, too stiff of a flex too low of launch angle and some loss of distance but it will also not
leave the target line. With all the different gram weights available of Scandium shafts this allows for more
flighting options of any golf shaft in the world. Scandium also is known as smart metal which means it has
memory. It wants to return to its original shape faster than any other metal. It is always better to fit to a
weaker flex than a stiffer flex because of its ability to handle the higher load. This is also one of the reasons
Scandium plays to lower CPM’s than a shaft of the same given flex or flight.
10.Scandium shaft weights move in a much smaller linear increase in stiffness than steel shafts do. Zone
frequencies and shaft profiles of a 90g Scandium shaft look almost identical to a 110g shaft, a 113g shaft
looks almost identical to a 125g shaft and so on. This was done to create 3 flexes within a given weight
range for different OEM head weights. A LIGHTER SHAFT DOES NOT NECESSARILY MEAN A WEAKER FLEX;
A HEAVIER SHAFT DOES NOT NECESSARILY MEAN A STIFFER FLEX; SCANDIUM MOVES IN A
DRAMATICALLY SMALLER LINEAR INCREASE IN WEIGHT TO STIFNESS RATIO THAN ANY STEEL SHAFT
PRODUCED TODAY. I can make an A-Flex R-Flex and Stiff-Flex out of 80g shafts but not an X-Flex. On all
other weights I can make all flexes including X-Flex but no A-Flex. Once again I can only do this because of
the properties of Scandium and our patented 2 visible steps and 3 invisible step patterns. Club fitters and
OEM’s should look for 3-7 playing weights. Example 117g set, (130g-151g) 110g set, (122g-134g) 105g set
(117g-131g), 100g set (112g- 126g), 90g set (102g-116g), 80g set (92g-116g) and a 70g set (82g-90g).
11. Since we are comparing Scandium to constant weight taper tip shafts lets discuss the difference in geometry and flex between the shafts. (see insert for True Temper geometry) To make their set constant
weight between each shaft wall thickness and weight has to increase as you move towards the wedge shaft.
The biggest difference in shaft comparison is that the True Temper shaft does not change in geometry
between individual shafts, same butt section and mid section only the tip section differs. Notice that the butt
dia. is different on the R flex 0.580 and 0.600 on the S, X flex. Since the Scandium shaft is made from a
blank, the butt section is going to be longer on the 3 Iron than on the preceding Irons and the butt dia. is the
same 0.601 for each flex. To fully understand the difference between steel and Scandium shafts is to
understand the properties of Scandium. Steel shafts are butt stiff and depending on the individual shaft
geometry will result in a high or low kick points or flex difference. This butt stiff leads to utilizing only the
lower beam section of the shaft when flighting or flexing the shaft, but Scandium properties lead to a soft
butt section and plays a major role in flighting or flexing of the shaft. The whole beam is utilized when
determining the ball flight of each individual Iron. The butt section is around 13 inches on the 3 Iron and
decreases in length to 11 inches on the wedge. Decreasing of a soft butt section leads to a decrease in
launch angle; therefore an increase in length of a soft butt section leads to an increase in launch angle. More
tipping is required on the longer Iron shafts than traditional steel and less tipping on the shorter Irons. This
along with the fact that we’re increasing in 2g increments per Iron this gradual increase in weight and wall
thickness leads to a much tighter tipping profile. Now you can see why I have said this is the most flightable
golf shaft in history. If an amateur has trouble hitting his long Irons up in the air you can decrease the
amount of tipping without losing the constant weight and the ball flight goes up. If a pro wants to decrease
the launch angle on both his/her long Irons and wedges increase the amount of tipping without the fear of
losing its feel. A typical set made with a 250g 5 Iron head in 6g increments made to a firm flex at D-1 is as
follows (3I-3/4”)CPM-296 (4I- 3/4") CPM-301 (5I-3/4”)CPM-307 (6-3/4”)CPM-313 (7I-1”)CPM-319 (8I-1 1/2”)
CPM-324 (9I-1 3/4”)CPM-330 (PW-2") CPM-336. Now if you take this set and move +/- 1/2” you can
personally flight it toward your needs. When I fit a pro or a top amateur I start with the 6 Iron and find their
best setup (length, flight, shot dispersion, distance, static weight and swingweight). I then move back to the
5 Iron and ask if they want the flight to be lower, higher or the same for each club until I reach the 2 Iron, then
I do the same for the 7 Iron through the wedges. Not surprising when dealing with pro’s the most common
set up is lighter shaft weights on the 2, 3, & 4 Irons but a strong tip 1 1/2”. Then move in 2g-4g between shaft
blanks after the 4 Iron, but I only move to a tip of 2 1/2” on the wedges +/- 1/2”. The choosing between 2g-
4g is based on the players feel, which is only a difference of 1g-2g on the shafts cut static weight, and also a
small increase in swingweight. If you were to look at the swingweight of the set it may look like this. 2I D-O,
3I D-O, 4I D-O, 5I D-1, 6I D-1, 7I D-1, 8I D-2, 9I D-2, PW, GW, SW D-3.
12.You would think we would run out of technical advantages of Scandium over other shaft properties (steel,
graphite and titanium) but we haven’t. One of my favorites is its vibration dampening ability, called
ShockBlok, which protects our body’s joints, tendons and ligaments during continuous impact with the ball
and the ground. The variable wall thickness and distinctive properties of Scandium alloy results in an almost
300% more shock absorption than steel shafts. The best way to explain this is to picture a bell made out of
steel and to strike it, the bell would vibrate at a high rate of oscillation and ring. This vibration effect is what
travels into our hands and body from steel shafts and gives us the infamous stinger feel. Now if you make a
bell from a Scandium alloy which is a softer tensile material than steel no vibration or oscillating occurs so
the bell doesn’t ring. This dampening effect only absorbs the high frequencies not the low frequencies, so I
can still feel the proximity of the ball on the face of the club but without the adverse effects. This is why we
have to be careful when fitting Scandium because we have always associated a harsh feel with flex, the
stiffer the shaft the harsher the feel. Scandium has been said to have the feel of a hot knife going through
butter. This feel can fool the player the first time they experience Scandium, I’ve had players turn to me and
say this shaft is too weak on the first couple of swings only to realize that the ball flight was perfect for
them. I personally had the same experience; I couldn’t believe that I could get my preferred launch angle and
not experience the harsh feel that I have come to be associated with my flex for so many years.
13.So what is MOI (moment of inertia) or (mass of inertia) the latest craze in golf terminology? It is
technically a body’s resistance to angular acceleration about an axis. As an object (club head) gets heavier
or as the weight is distributed farther away from the center of gravity (CG) of the head or axis of the shaft
the MOI increases. Another way to explain MOI is the spinning merry-go-round on a playground; if I put ten
(10) of my friends that weigh 200lbs. ea. into the center near the axis it would take very little inertia to spin
them, or low MOI. But when I move them away from the center and move them towards the edge I would
need a lot more inertia to spin them. Or an ice skater spinning fast with her arms close to her body has a low
MOI. But by extending her arms the spin slows down, a result of an increase in MOI. So why make a head
with high MOI? Well when the club head incorporates perimeter weighting the higher the MOI about its
vertical CG axis, the less the head will twist on off center hits and there will be less loss of distance, it is
more forgiving. But this will also put more and more MOI on the shaft when you move weight away from the
shaft axis. So why use lightweight shafts? The lightweight shaft phenomenon has always been expressed in
terms of a lighter total weight golf club that has a heavier head weight which can be swung faster,
consequently provide a greater distance. The equation is E=1/2 (MV2) or a more descriptive terminology as
follows; Energy of a club head applied to a ball at impact = 1/2 (club head weight (mass) times club head
speed (velocity) squared). Well let’s go back to the ice skater, remember when the skater was spinning the
fastest, their arms where close to the body, and when they extended their arms, they slowed down because
they had moved more weight away from the body axis or spine. This is the same process a golfer goes
through when swinging a heavier club around their axis or spine a higher MOI a slower turn. Compared to a
lighter club a faster turn low MOI. As you can see, if we can decrease the weight of the club shaft by 20 to 40
grams we can make it much easier to increase club head speed. But this lightweight shaft causes us to put
even more MOI on the golf shaft. This is because the club head has to increase (yes increase) in weight
when you decrease the shaft weight to maintain the same swingweight. If I replace a 123g steel shaft with a
swingweight of D3 and replace it with a 98g shaft a reduction of 25g it will decrease about 3 swingweight
points to D0. (based on a 14” fulcrum swingweight machine) I will need to add about 7g to the head to bring
it back up to D3. This is still a total static weight reduction of 18g, unless I only bring it back to D1.5 an
addition of only 3.5g to the head, and now a 21g reduction in static weight. This is why I ask the OEM’s for
their heaviest head weights of that model so I don’t change the CG of their head. If I’m making sets of clubs
with 70g shafts I need to have this weight to maintain D2. All these changes increase shaft loading and
affect shaft performance in three critical directions. 1. Torque (resistance to twisting around the shaft axis)
2. Bending in the swing plane (the flex or the loft of the club) 3. Ovaling or dropping in the plane (were the
impact occurs on-the-face of the club). The Scandium golf shaft has the lowest torque ratio 0.5, the
greatest ability to resists ovaling and the largest range of flex of any light weight shaft on the market today.
All this leads to a more solid impact, resulting in improved control and shot dispersion.
