For centuries, splice neck joints were the territory of wood head
clubs, and wood head clubs only. That ended in 1910 when Frank Murray
received a British patent for his splice neck iron, which now stands as
the only iron made with a splice neck joint in the history of the game.
This club is a fine example of Murry's splice neck iron. Both the top and bottom of the hosel are missing whipping. Consequently it allows the top of the iron's neck and the bottom tip of the shaft to be seen.
For more on the only iron club to be made with a splice neck joint, see TCA2 v1 p180.
