Irons or Wedges - more or less grooves?

Hi fellow GRians, is there a standard set for number of grooves allow on e face of e iron wedge face? More better than less, or otherwise? Hope can enlighten, tks

Grooves are suppose to generate spin on the golf ball right?

I remember reading an article on golfwrx about this... And how the rules were relaxed for the number of grooves allowed on the club face... This allowed the spin to increase and together with the loft angles, the carry distances increased...

Hi bro Paul,

Interesting topic and I did some googling up and found this on randa.org. I may be wrong maybe some gurus and can shed more light on this but reading from the web, it seems that there isn't a fix number of grooves that is on the club face, as there is slighty different shape and sizes of the face but there is a guideline on the gaps between the grooves to limit the grooves on real estate of thr face. So the more may be better but there is a guideline for conformity. Cheers

Extract from the randa.org website:
Impact Area Markings
If a club has grooves and/or punch marks in the impact area they must meet the following specifications:
(i) Grooves

• Grooves must be straight and parallel. • Grooves must have a plain*, symmetrical cross-section and have sides which do not converge. • The width, spacing and cross-section of the grooves must be consistent throughout the impact area. • The width of each groove must not exceed 0.035 inches (0.9mm), using the 30 degree method of measurement on file with The R&A. • The distance between edges of adjacent grooves must not be less than three times the width of the grooves, and not less than 0.075 inches (1.905mm). • The depth of each groove must not exceed 0.020 inches (0.508mm). • *For clubs other than driving clubs, the cross-sectional area (A) of a groove divided by the groove pitch must not exceed 0.0030 square inches per inch (0.0762 mm2/mm). • Grooves must not have sharp edges or raised lips. • *For clubs whose loft angle is greater than or equal to 25 degrees, groove edges must be substantially in the form of a round having an effective radius which is not less than 0.010 inches (0.254mm) when measured (using the two circles method), and not greater than 0.020 inches (0.508mm). Deviations in effective radius within 0.001 inches (0.0254mm) are permissible.

Tks guys, for the wealth of info but some golf reseach out there after running some comparision with same loft club having plain face, milled face and grooves + milled face, actually found less or no grooves no milling can actually create more spins and distance, so
