Ferro offers four iron shafts across steel and graphite. The choice affects the weight in your hands, the timing of your swing and how you deliver the clubhead. Start with a weight you can control; choose an upgrade only when it earns its place in your build.

The four options at a glance

These are the current choices for a Ferro complete 4–PW set. Prices shown are shaft upcharges for the seven-club set, added to the base set price. Availability and the live total are shown in the builder.

KBS Tour · steel · included

110g Regular · 120g Stiff · 130g X-Stiff. The starting point if a traditional steel weight works for you.

KBS $-Taper · steel · +$105/set

110g Regular · 120g Stiff · 130g X-Stiff. A different profile and black PVD finish; compare its flight and feel with Tour.

KBS TGI · graphite · +$315/set

60g Regular · 80g Stiff · 100g X-Stiff · 110g X-Stiff+. The widest move toward a lighter shaft in the Ferro lineup.

Fujikura AXIOM · graphite · +$455/set

95g Regular or Stiff · 105g Stiff or X-Stiff · 125g Stiff or X-Stiff. A graphite option that also reaches substantial weights.

KBS Tour: the included reference point

KBS Tour is our stock steel choice. Its 110g, 120g and 130g offerings cover three familiar weight-and-flex combinations. If you already play a fitted steel shaft around one of these weights, start here and compare from a known baseline.

Included does not mean a compromise. If Tour gives you repeatable contact and the flight you want, there is no reason to pay more simply because another option exists.

KBS $-Taper: another steel feel and flight

The $-Taper is offered at the same 110g Regular, 120g Stiff and 130g X-Stiff choices, so you can compare it with Tour without automatically jumping to a different nominal weight. KBS describes the $-Taper as a mid-trajectory, lower-spin design. That is a design aim, not a promise that every golfer will produce the same numbers.

At +$105 per set, look for a flight, landing angle, dispersion or feel you genuinely prefer. Less spin by itself is not an improvement if it makes the ball harder to stop.

KBS TGI: graphite with a broad weight range

TGI starts at 60g Regular, with 80g Stiff, 100g X-Stiff and 110g X-Stiff+ also available. It gives a golfer a way to explore lighter total shaft weight while keeping an iron-specific graphite option in the build.

The listed weights come with different flexes. If you are comparing 60g TGI against 120g Tour, you are changing more than the material. Judge the finished shots and how comfortably you can repeat them, rather than assuming the lightest option will go farther. The set upcharge is $315.

Fujikura AXIOM: graphite without assuming lightweight

AXIOM uses Fujikura's VeloCore technology. Ferro offers 95g in Regular or Stiff, 105g in Stiff or X-Stiff, and 125g in Stiff or X-Stiff. The 125g choice makes the point clearly: graphite does not have to mean a light shaft or a soft flex.

Its +$455 set upcharge is the largest of the four. Compare it against an appropriately weighted steel or graphite choice with the same head and ball. Pay for the result and the feel you can repeat, not for the material label.

How to choose yours

Begin with your current fitted shaft if you have one. Change one variable at a time where possible: weight first, then compare the available shaft and flex combinations. Hit more than one good shot. Watch your typical strike, carry distance, peak height, descent and front-to-back distance pattern; listen to what feels easy to repeat.

At our TrackMan fitting facility in Hawaii, those measurements can inform the choice, but they belong to the golfer being fit. A printed flex label does not have an identical meaning across every model, and no shaft guarantees a particular launch or spin window for everyone.

Your Ferro MC or CB build can then pair the chosen shaft with the grip and club specifications you actually want. For a lower-commitment on-course check, the custom test 7-iron lets you try one build before deciding on the matching set.

The best shaft is the one that helps you deliver the head consistently. The most expensive shaft does not automatically win.
