For the first time in history, every single iron in a major brand’s family comes from the same Japanese forge. Srixon has done something no other maker has quite pulled off with their new second-generation ZXi lineup. The entire set, from the player’s blade to the utility iron, now bears the stamp of Endo Manufacturing.
This facility is the same place where Tiger Woods forged his famous Titleist 681T blades. He used those irons during his historic “Tiger Slam” run where he won four straight majors back in 2000 and 2001. Endo is known for strict quality control and deep skill with soft steel.
According to GolfWRX, the ZXi family includes four distinct models to cover every type of swing. The lineup features the ZXi7 Players Irons for the best ball-strikers and the ZXi5 Players Performance Irons for a wider range of skill. There is also the all-new ZXi5+ Players Distance Irons for those chasing extra yardage, plus the ZXiU Utility Irons to fill the gap between woods and irons.
The Endo Connection Srixon has used Endo Manufacturing before for select forged clubs, but this launch changes the game completely. The new ZXi iron lineup becomes the first family of irons to all be fully forged by the facility. This move ensures that the feel and consistency remain identical across the entire set.
Casey Shultz, Srixon Senior Product Manager, explained the philosophy behind the shift in a company release. “From the materials we use to the way each head is forged, shaped, and weighted, every decision was made with feel in mind,” Shultz shared. “It’s the hallmark of Srixon Irons and something we’ve always refused to compromise on.”
The goal was to push that philosophy even further while keeping the performance golfers expect. Shultz noted that the new clubs deliver a rewarding sensation when struck pure, something players instantly recognize.
Smart Tech in a Soft Head Forging usually means traditional methods, but Srixon is mixing old-school craft with new digital tools. The engineers used artificial intelligence to design the face structures for the ZXi5, ZXi5+, and ZXiU models. This system, called “MainFrame iQ,” ran thousands of simulated impact scenarios to find the best shape.
By reducing face mass by as much as 8% and moving weight around, the team achieved faster ball speeds. They also increased forgiveness and raised the MOI for more stable shots across the face. The ZXi7 player’s iron uses a different system called “PureFrame iQ” to stiffen the impact zone right behind the sweet spot.
This design reduces unwanted face deformation while making the club more stable. It utilizes mass more efficiently than the previous generation to give better players a soft yet responsive feedback. The result is a club that feels like a blade but plays with the forgiveness of a game-improvement iron.
Why Consistency Matters Now The combination of advanced manufacturing processes and premium materials allows Srixon engineers to execute precise forging techniques. They need these exact methods to build the new i-Forged platform. The facility delivers exceptional consistency from head to head, which is rare in mass production.
Every golfer knows that a mismatch in feel can throw off a round. Having the same forging process for every iron in the bag removes that variable. The tuned weight distribution update also incorporates additional perimeter weighting in the long irons for forgiveness.
This approach keeps the set playing as one unit from the short irons all the way to the utilities. Golfers who have struggled with inconsistent distance gaps will find a solution in this new lineup. The technology is there, but the feel remains the priority.
