This refers to a specific putter design. It indicates a putter head manufactured using a milling process, incorporating distinct weight and balance characteristics. The “seven t” likely denotes a particular head shape or style within a putter line, and “db” most probably represents a specific weight distribution or balance point within the putter head. As an example, it could be a putter with a milled face, a seven-shaped head, and a double-bend shaft for optimal balance.
Such a putter design offers precise manufacturing and consistent performance. Milling allows for tight tolerances, contributing to a predictable roll. The specific head shape and balance point are engineered to suit particular putting strokes and preferences. Historically, milled putters have been associated with premium quality and enhanced feel, often favoured by skilled golfers seeking optimal control on the green.
