Newly Released Zero-Torque Putter "ZT-STELLA" A critical mistake in putting. This is a directional error caused by a slight misalignment of the face angle at impact. No matter how well you read the line, or how well you judge the distance, if the face is not aimed in the intended direction, the ball will not go into the cup. Especially in putting, a deviation of just 1 degree can cause a 2m putt to miss, showing how small deviations greatly affect the outcome. Missing short putts. Not hitting the intended line. Your stroke feels fine, but the ball lips out at the edge of the cup. For golfers struggling with such issues, the "zero-torque" putter, a new structural design, has rapidly gained attention in recent years. ■ The New Structure "Zero-Torque" Rapidly Gaining Traction in the Golf World A zero-torque putter is a putter with a new structure that suppresses the extra force that tends to open or close the face during the stroke, making face control easier. In conventional putters, the misalignment between the head's center of gravity and the shaft's axis makes the face prone to opening or closing during the stroke. This slight deviation becomes a directional error at impact, often leading to missed short putts or failing to hit the intended line. On the other hand, the zero-torque structure aligns the center of gravity with the shaft axis, making it easier for the putter to naturally stabilize the face during the stroke, reducing the need for extra hand manipulation or force, which has garnered attention from many golfers. Misalignment between the center of gravity and shaft axis generates twisting (torque) force. In fact, in recent years, the presence of zero-torque putters has rapidly increased, particularly among professionals and golfers knowledgeable about equipment. However, while its benefits are widely known, conventional zero-torque putters have also revealed certain challenges. ■ The Benefits of Zero-Torque are Appealing, But Some Find Them Unsuitable The
