TECHNOLOGY
Groove Comparison
- Reverse-Cut Grooves
- To keep loft angle the same while producing the maximum possible spin, grooves that grabs the ball were added to the angle, neglecting the R&A rules.
- Double Milling
- Ignoring the R&A rules, we machined a wide double milling into the face to generate severe friction.
- Slice Line
- A slice line increases the effectiveness of shots that open the club's face.
Regulation Wedge
- Grooves on Regulation Wedge
- The R&A rules dictate the width, depth, and spacing of grooves, which limits the amount of spin.
- Milling on Regulation Wedge
- The R&A rules specify that grooves cannot affect spin, so they are used for drainage instead.
- Regulation Wedge
- Due to the R&A rules, there are no grooves for increasing spin when opening the club's face.

TEST DATA
Comparison of Spin -- 20-Yard Approach
We compared the DIA CROSS SPIN with a regulation wedge.
TrackMan measurements revealed that the non-regulation DIA CROSS SPIN produced more spin than regulation models, allowing players to aim directly for the pin.

* Average values for 10 balls hit with each 58° test club.
* RPM refers to revolutions per minute.
* Results may vary according to weather, grass conditions, and the golfer's swing trajectory.
BOUNCE
Middle Bounce (50° • 52°)
A middle-bounce angle allows people who have sharp or shallow swing trajectories to feel the bounce of the club.
This makes it easy to hit shots in a variety of conditions around the green.
High Bounce (56° • 58° • 60°)
A high bounce and wide sole allow bounce to be easily felt.
Also suitable for escaping bunkers, high bounce provides a comfortable follow-through in many different conditions.
SHAPE
Traditional shape makes it easier to set your stance
The club's shape features a sharp topline and smooth curve between the face and neck. A slight gooseneck makes it easier to grab the ball on the downswing and generate spin.
A favorite among golfers, this shape allows players to make their shots as they envision them under any conditions.
SHAFT
Lightweight Steel Shaft from True Temper
The club uses a lightweight steel shaft manufactured by True Temper, whose Dynamic Gold shafts have been used by many top pros since their introduction 40 years ago. A medium kick point pushes the head in a way that improves control.
You can also match the lightweight steel to the flow of your irons.
Original Lightweight Carbon Shaft
Rare among single wedges, this carbon shaft has been designed to standard specifications.
It can also be matched to the flow of your carbon irons.
The low kick point allows even golfers with slow head speeds to push the head and increase spin amount.
Recommended Settings
Here are some examples settings for matching with the irons you use.
You can select the optimal loft to follow your pitching wedge.
And since the BMF is also available with a carbon shaft, you can choose a club that doesn't feel off or uncomfortable.
