groove sharpeners on vokey

A common subject on here..
The problem is with the size and depth of the grooves.
You can sharpen them but you have to make sure the grooves stay within permitted dimensions.
Take out too much metal and your grooves become nonconforming and therefore illegal to use in comps.
If you're able to measure microns then carry on.
 
why do you think that, i found my ping wedge was great when new but lost its stopping power after a while

How long until you found it lost its stopping power ? Thought you have only been playing golf for a year ??
