Shaft Puring is kind of as it says on the tin,will try and explain as best I can.
No matter the quality of manufacture no club shaft is absolutely perfect,they all have some form of inconsistency with steel being the most stable.
In order for the shaft to perform at its best it is vibrated to find its optimum plane and then fitted to the head in accordance.
This is most easily observed on my woods as the logos are all pointing in different directions as opposed to perpendicular to the grip/head. For example my driver logo is on the back of the shaft and my 3 wood points at ten past 12.
When I had my Driver done the fitter put my existing club in the machine and turned it on,the head moved in a sort of mad figure of 8. He then rotated it until it moved on one plane and the face was pointing at the wall!
If I am honest,in the irons I am nowhere near good enough to say that it makes a significant difference,what has helped is having all the shafts matched and swing weighted.
If you want more you can look puring up on the web for a proper techy explanation.
Sole cutting or grinding is shaping the sole to suit the playing charactersitics that you like. Most Tour Pros have the heel and toe of their wedges cut away to help playability. Cleveland have brought out a set of wedges already cut called the DSG range (Double Sole Grind). It has certainly helped me with pitching and chipping and means I can really open my 58 for flop shots off tight lies without bringing the bounce into play.
All a bit poncey to be honest but I do love my kit and it is a good feeling to know it was all built for you.
Playing rubbish right now tho so it all comes back to the muppet holding the stick really!
