These forged muscle back irons by legendary clubmaker Roger Cleveland are designed specifically to meet the demands of the best players in the world. With Tour styling and soft carbon steel construction, these irons provide precision shot-making with incredible feedback and workability. The flighted CG (center of gravity) design and X-muscle back generate consistent, Tour-level trajectories with unparalleled playability in a blade.
Forged 1020 Carbon Steel Construction: Provides unmatched feel and performance, giving elite-level golfers incredibly soft, responsive feedback at impact.
Tour Styling: White Chrome finish delivers the preferred aesthetics for Tour players, with a very thin topline, narrow sole and shorter blade length for maximum workability in various turf conditions.

Pro-Jo krub,
It's seem that Swing Weight for 5-Iron is so more obvious than the others...
Or these swing weights along the club were designed by CallAway based on conceptual design of "Unsurpassed Customization"
I might make my club fitting of swing weight like here above someday.. ^_______^
พอยิ่งมาเช็คดูก็จะเห็นได้ว่ามาตรฐานสำหรับไม้กอล์ฟนั้นแทบจะไม่มี เพราะทำยากมาก แต่ละแบรนด์ก็ต่างกันไป แต่ก็จะมีค่าความคาดเคลื่อนอยู่ราวๆ +- 1 ซึ่งก็ถือว่าเป็นเรื่องปกติครับ ไม่ว่าจะเป็นเรื่องของน้ำหนักใบเหล็ก,น้ำหนักก้าน กริฟ กาวและแท่งตะกั่ว ซึ่งก็จะมีค่าของความคลาดเคลื่อนอยู่ในตัวครับ
