The grooves were machined to the maximum legal size (I bought these in 2008 or 2009 before the rules changed to reduce the spin) and will spin noticeably more than any wedge that you can buy from the shops these days.
These are not legal for use on professional tours (too much spin) but are perfectly legal for use in club golf.
This club has been used for only 5-6 shots and is in very good condition.
