I have a set of Wilson FG-17 irons, purchased in 1981. I want to get a groove tool, to retool the grooves, but I don't know the shape of the grooves? I think they are V grooves, but can anyone verify this? I don't want to accidentally screw up the grooves with the wrong shape tool. And by the way, I play these irons regularly.
Also any tips on a good groove tool? Thanks.
