Two purpose-built putters. Two different approaches to creating a more repeatable putting stroke.
Armlock putting is designed to reduce unwanted wrist movement by bracing the shaft and grip against the forearm. The objective is a more repeatable shaft angle and a more consistent putting stroke from setup through impact.
Bracing the putter against the forearm helps limit changes in wrist and shaft angle during the stroke.
A more stable relationship between the hands, forearm and shaft can make the stroke easier to repeat.
On Lock uses a traditional armlock approach. Deadbolt uses Reverse Armlock Technology for golfers who prefer the dominant arm.
The approved engineering graphic explains the difference between conventional putting, traditional armlock, and Pinhawk's Reverse Armlock Technology without replacing the real product photography.
The On Lock and Deadbolt solve the same basic problem—creating a more stable putting stroke—but they do it with two different forearm relationships.
Designed specifically for the traditional armlock method rather than adapting a conventional putter head to a longer shaft.
Designed so the shaft can be stabilized against the golfer's dominant arm for a more natural-feeling reverse armlock setup.
Both models are designed around forearm stabilization, but the setup, shaft lean and loft requirements are different.
The basic fitting method is simple: assume your normal putting posture with your current putter, then measure from the butt end of the putter to approximately two inches below the crease of your elbow.
Add that measurement to the length of your current putter. For example, a 34" putter plus a 6" forearm measurement suggests a starting armlock length of about 40".
The final length should suit the golfer's normal posture and allow the butt of the putter to rest roughly 1–3 inches below the elbow crease.
Once the putting method is chosen, TSH Golf completes the build around the golfer instead of treating the product as a stock-length putter.
