Features and Benefits

* Model 770CFE irons represent the first set of irons designed with a forged steel, CNC machined, variable thickness face design

* The 770CFE irons are designed with a variable thickness forged face to offer golfers a little higher ball-speed-to-swing speed ratio than is possible with a conventional thick face iron design, but also to offer golfers a much better off-center hit forgiveness because of the variable thickness face design.

* Because irons increase in loft progressively through the set, the actual force of deflection of the face will decrease as loft increases. To help maximize the amount of face deflection as loft increases in the irons, the forged variable thicknessface design changes in face material composition and thickness. Thus, the #3 and 4 iron faces are forged from Carpenter 455 high strength steel and are designed with a variable thickness of 2.4mm/1.9mm.Then the #5, 6, and 7 iron faces are forged from 17-7 stainless steel and machined to a variable thickness of 2.5mm/2.0mm. And the #8 through wedge faces are forged from soft 304 stainless and machined to a variable thickness of 2.6mm/2.2mm.

* In addition, as loft increases in a set of irons, the actual position of impact on the face will change. To accommodate this natural tendency in iron impact position, the thicker center section of the faces changes in position through the set.

* Thus the 770CFE irons are individually computer modeled for face thickness dimension, face thickness position, and face material for each iron in the set to offer the best individual performance possible in a full set of irons.

* All 770CFE faces are CNC machined after forging to ensure precision in the face design. The CNC machining marks can be seen on the back of each face.

* The body of each 770CFE iron is designed to maximize the area of the face available for face deflection, as well as to move as much of the weight of each head further back from the face and shaft centerline to assist in launch angle.

* The sole design of the 770CFE is designed to keep a large amount of mass low, but by beveling the back edge of the sole the sole width is not so wide to ensure proper sole playability from all types of turf and lie conditions.

* 770CFE irons are finished in a bright satin polish finish, with all faces CNC machined for precision dimensional specifications.

Features and Benefits
	* 939H is designed to be a blended set of hybrid and solid body irons for maximum game improvement in the lower lofted irons, but at the same time to be a blended set in which ALL irons look like real irons and not like "half-woods".
	* 939H features 2-piece hybrid model design construction on the #2, 3, 4 and 5 irons for maximum game improvement and assistance in getting the ball up, because most 5-irons today do present some difficulty in generating a nice high shot pattern to most golfers. This is due to the golf industry's trend toward lower lofts on all ironheads.
	* 939H hybrid #2, 3, 4, and 5-irons feature a custom wall thickness designed to move the center of gravity farther back in the head from the shaft–a proven design feature for increasing launch angle. Such a wall thickness design is only possible through a 2-piece hybrid construction, and hence the slightly higher cost of the #2 - 5 ironheads.
	* 939H irons #6 through the wedges are a conventional deep cavity back with weighting low and toward the heel to assist in squaring the blade at impact plus keeping the mass lower to assist with launch angle.
	* A special feature of the 939H irons are the custom sole designs for each half of the full set design. On the #2 - 5-irons, where the nature of the design is to make a wider sole/body to move the CG back from the shaft, the sole design is cambered (radiused) in such a way as to keep more of the mass low on the iron. The camber thus reduces the area of the sole that will come in contact with the ground/turf for a greater percentage of solid impacts and fewer "fat" shots, while the greater sole width keeps the CG low for more ease of play. On the #6 - wedges, a true full radiused sole design is incorporated to also minimize surface contact with the turf for more solid shots and fewer "fat" shots for a more medium sole width.
	* All 939H irons are precision investment cast to ensure the designed wall thickness and CG locations in each head.
	* For golfers who truly fight getting the ball up high enough to carry far, TWGT recommends the use of either of the .335" tip diameter high trajectory shaft designs (GI-335 graphite or Series 5 Steel .335 tip) in the 2-piece hybrid 939H ironhead designs. Installation of these shafts is facilitated by the specially designed coiled metal shims.
	* 939H irons are ideal for the golfer who wishes to play a full set of irons but usually hits the long- and mid-irons low and off-center.

Features and Benefits

* Model 991C irons are a classic profile shape full cavity back game improvement design for golfers who search for a high level of off center hit forgiveness but with a classic shape and size head design.

* 991C irons also feature a slight bottom cavity undercut weight distribution to keep a substantial amount of weight very low and closer to the sole to assist with increasing trajectory.

* 991C irons are designed with a bold rear backpad weighting that is cut away in the center to accentuate the heel and toe weight on the back of the head to assist with the off-center hit forgivness of the design.

* Progressive offset on the 991C ranges from 5mm on the #3 iron to a slight 2mm on the wedges. The offset is designed to not appear too strong in the playing position, but still to allow its contribution to slightly increasing the launch angle and allowing a slight more rotation of the face back to square on the downswing.

* Lie angles are progressive from slightly upright on the long irons to standard on the short irons, while the high loft wedges return to a slight upright lie to allow better set up for short shots where the golfer grips down.

* Loft angles are designed to be slightly strong, yet not so strong as to reduce launch angle too much or make the long to middle irons too difficult to properly get airborne. 991C includes a gap wedge (AW-51°) to prevent any gap between yardages through the short irons and all wedges.

* Sole angles are progressive from a slight 2° bounce on the #3-iron, but not so pronounced on the short irons to make shots from tight lies easy to manipulate. SW is designed with more bounce at 13° for ideal use by golfers who may have difficulty with bunker shots, as well as for deeper to slightly softer sand conditions.

* Sole design is cambered from front to back with both the leading and trailing edges 'broken' to allow ease of play from either bent or bermuda, as well as rye or bluegrass in the rough.

* Model 991C irons are precision investment cast to allow the shape and undercut of the back cavity to be accurately created. Head material is pure 431 stainless steel which is heat-treated to allow ease of loft and lie alterations for customizing, and passivation treated to increase surface durability.

* Finished in a bright smoked satin polish with glass bead blast highlights and metallic coated back cavity surface.
