That said, on a sandwedge, I can see this making a difference. Sand is incredibly abrasive, so it will wear the edges of grooves. However, this tool removes material, so it will make grooves wider, deeper, and non conforming. You can't remove metal from a club, without making it non connforming. Any one using this tool is a cheat.

Whether or not it does render the club illegal is a moot point,but which G C has the equipment to test the grooves.

This is true 99% of clubs would not be able to measure the groves. Although the groves have to be within a specified size tollerance, it's not so much the size (I don't think the depth of grove would make to much difference, the width would be more significant) but the sharpness of the grove. When manufactured the groves have to have a very small radius on the edge and I belive it's the removal of this radius thats giving people more spin which in turn makes the clubs ilegal. The sharpness of the groves can be felt by running your finger across the face of the club...you would be amased at what you can actually feel.

But back to your point, no I don't think this would be picked up by most clubs, so people will get away with it.

The depth of the grooves will make a huge difference playing from the rough. It is a volume thing, being able to clear the grass etc from the face of the club. The deeper the grooves, the more volume available for debris. If anything, this is more important than width. Especially if you don't clean your grooves often enough.

I think we're going to have to agree to disagree on the grove depth. I can't see horizontal groves displacing vertical grass blades no matter how deep they are, thats why it's so difficult to get spin out of the rough.

 

[USER1999]

It is a question of displaceing debris. The grass gets in the way, between the club face and the ball. The bigger the volume of the grooves, the more grass you can squash into it, allowing more of the club face to impart spin onto the ball. The ball forces the grass into the grooves.

 

[Twire]

So do you not think it would be easier to force grass into a wide grove rather than a deep grove?

 

[USER1999]

No, because less of the club face would be left to contact the ball, which is, after all, the whole point of having groves in the first place.

 

[Twire]

As I said, I think we'll have to agree to disagree on this one.

Thanks it is.

I am lucky enough to have a lovely course on my doorstep. I live the othe side of the town about 5 minutes away.
