Correct me if I’m wrong but doesn’t the specific sweet spot depend on a) the club number and b) the club make and model?
No. The sweet spot is generally in that exact spot for all irons. You’re supposed to hit the ball first with a descending blow, then the turf. Why would a club manufacturer make the sweet spot high on the face?
Having said that, with player improvement irons, the sweet spot can be much larger. Tech nowadays focuses on pretty much that. Old saying in golf is, “It’s not how good your good shots are. Everyone can hit a good one. It’s how good your bad shots are.” So by making the sweet spot larger for a higher handicap player, it gives them a better chance of the shot still coming out ok on miss hits.

This is interesting and makes sense. As lower lofted clubs tend to have a more sweeping attack of angle. Still only talking 0-2 mm though between a 9 and 4 iron. So 1 grove.
Why is there grass on the face from a tee shot on a par 3?
Also, this is commonly called a flyer, which usually happens when the ball is sitting up in the rough and you make contact a few grooves too high on the face. Between the high contact and the grass between the ball and the club face, you essentially get a knuckleball that usually flies 10ish longer than an actual pure shot.
This is why often, you will see pros actually clubbing down from the rough if they think they have a flyer lie. Flyers are deadly.

Thank you for explaining this! I have recently been getting into golf and have heard the term flyer lie thrown around here and there but never really understood the concept!
