Isaac Mackie sought to overcome the perceived weakness of both socket and splice neck woods by combining a socket and splice neck into a two-piece shaft. 

As designed by Mackie, the club offered here is made from three separate pieces of wood: the head and a two-piece shaft.  The two-piece shaft consists of a full length piece and an intermediate piece. The full-length piece splices onto the back of both the neck and the upper part of the intermediate piece.

The beautiful workmanship that combined the two pieces of the shaft make the splice between those two pieces difficult to see, but it is definitely visible upon close inspection. Three sections of whipping help hold the two pieces together.  The lower part of the intermediate piece sockets into the head.

Mackie received a US patent dated June 2, 1914, that covered his club. He believed his unique design would combine the distance provided by socket neck drivers with the accuracy provided by splice neck drivers. 

The club offered, marked RNM on the sole along with its patent date and "Pat Applied For" to reference the 4-way backweight, was produced by Spalding in 1922. 

This club is all original, complete with its original grip and original insert that covers the bottom half of the face. For more on this club, stamped with the name of the seller "R. Cameron", see TCA2 volume 1 page 168.
