The new putters will be released in the spring of 2026.

Hirota Golf Stealth Chipper C-SOLID Main
1. Forged Stealth Chipper C-SOLID: A club that helps you pursue functionality and aesthetics
[Development concept] There is a club called "Chipper" for golfers who are not good at approaches. We know it is advantageous for score making, but to golfers who hesitate to put it in their caddie bag because of how chipper the shape is. It does not spoil the appearance even if you put it in your caddie bag. Although it looks like an expert's iron, it is actually a helpful club that can be used around the greens and in trouble situations.

Hirota Golf Stealth Chipper C-SOLID Introduction
Aesthetics: Handmade forged soft iron forging in Ichikawa-cho, the birthplace of Japanese golf production, is finished by craftsmen polishing one by one. The appearance is a muscle back shape favored by professionals and experts, and the C in the sole engraving is not a C for chipper, but a C for control irons to control your game. The C on the sole is not a chipper, but a control iron to control your game.

Heavy head: The head weight is set to 330g target and the club balance is set to E-over to create an automatic that does not stop once it starts moving. Reduces looseness such as hands stopping even under tension. Also, even in situations where the tee shot is bent and you want to get it out to the fairway, the heavy head will keep you in the rough and provide stable game control.
Tooth Drop Grind Sole: With a normal leading edge, the head is so heavy that it has a strong force to fall due to gravity, and the teeth stick into the ball if the ball is slightly off-center.

65° lie angle: When the club is designed to be upright, the chipper is more pronounced, and when it is flat like an iron, the weight of the head causes the face to open up during the stroke, resulting in many mistakes. After testing, the 65° lie angle was designed to make it easy to hang and stroke like a putter.

MEGA Zero Gravity Putter: Fusion of Self-Support and Zero Torque
[Development Concept] Aiming to eliminate 3-putts, score making with the putter. Eliminate 3-putts by improving direction, repeatability, and distance, and reduce the number of putts to score. Automation of the stroke and the fusion of the self-supporting and zero-torque system that rolls the ball to the imagined line.
Revolution in aiming: The putter stands alone, so the line can be checked from behind. This eliminates the greatest stress of wondering if the direction is correct. The putter stands on its own, eliminating the anxiety of aiming and allowing the player to address the ball with confidence. Also, because it is self-supporting, it is possible to address the putter as per the lie angle, which improves stroke reproducibility.
It is also useful for practice to check how accurately you are addressing the line you have imagined and to correct any quirks.
Revolutionizing the stroke: The shaft is inserted at the center of gravity of the head, and the specifications are such that almost no torque is generated, so the head opens and closes almost never. The face always moves in the direction of the target, so it is easy to suppress the influence of wrist movements and other movements, and the design allows for automatic strokes.
Straight line: The 6061 Aluminum body, which is used for aircraft parts, is used for its high design freedom and high MOI, and the precision CNC machined body provides a large moment of inertia for a stroke without blurring and powerful straight-line performance.
