Club-heads

 

Our iron and fairway wood club-heads are cast from the highest grade 17-4 stainless steel in the golf industry.  Unlike other brands who use cheaper 431 steel that can result in the specifications of the club-head (loft and lie) changing through normal play, our club-heads are designed to last a lifetime.

 

Shaft Optimization Process

 

We use our own Shaft Optimized stepless steel golf shafts in all 1 Iron Golf clubs. Shaft Optimization is a proprietary process we developed whereby the playability characteristics of the shaft are optimized for peak performance in relation to the design specifications of the club-head. This forms a perfect mechanical marriage and balance between the individual components which produces the ideal shaft loading and ball trajectory for the golf club regardless of the strength or swing speed of the individual golfer. While other golf club manufacturers concentrate on non-standardized flex ratings and other shaft performance myths we have found that shaft optimization is the major key to golf club playability.

 

The design specifications of our stepless steel golf shafts precisely match the design specifications of our club-heads which produces a perfectly balanced golf club (all other brands use stock shafts with no balance criteria whatsoever).  Once this perfect balance is achieved there is no such thing as flex ratings.  In other words, the golf club will perform at its peak performance level regardless of swing speed or strength.  Our golf clubs are played by professional golfers with extremely high swing speeds and played by women and senior golfers with very low swing speeds.  The results of our studies and testing over the past twelve years have shown that our shafting method produces the highest level of performance for any golfer.

 

We are also the only golf club manufacturer to perform shaft flex plane orientation as part of our Shaft Optimization Process. If a golf club is shafted without regard to the inherent flex plane of the shaft it will try and rotate around its axis to a position of stability during the swing which creates an oscillation between shaft and club-head. This oscillation results in the club-head literally wobbling through impact. However, when the shaft is correctly oriented in respect to its inherent flex plane it will resist twisting to any other position when placed under load and will remain stable and on-line through impact. The feeling is that the club-head is riding on rails through the impact zone. The result is a much higher degree of ball striking consistency with a maximum transfer of power at impact. It is important to note that over two-thirds of PGA Tour players have had the shafts in their golf clubs oriented for flex plane stability. This is an additional step that is not included in the  manufacturing process by any other golf club manufacturer.

 

Due to the precise balancing of club-head and shaft resulting from our Shaft Optimization Process a 1 Iron Golf club produces much less of the vibration and shock normally associated with steel shafted golf clubs.  Consequently, our 1 Irons possess the comfort of a graphite shafted club with the inherent performance consistency of steel.  It is worthwhile to note that many of our customers are former graphite shaft players.

 

Grips

 

We only install oversize grips with reduced taper on our golf clubs.  We have found through our testing over the past twelve years that this type of grip produces a much greater degree of surface to skin contact than standard grips and more “meat” under the right hand which allows for a greater transfer of swing force and a much higher degree of control and accuracy.  ...click here for info on grip sizing

 

Quality Control

 

Every single one of our golf clubs goes through a twelve point quality control inspection process before being shipped to the customer.  This is unlike other brands who mass produce their golf clubs through factory assembly lines in China by unskilled Chinese workers with very little quality control inspection whatsoever.  Our golf clubs are custom built by highly skilled club-making professionals who constantly check and double check the dynamic and custom fitting specifications for each individual order and we keep these specifications on file for each customer.
