Is your dynamic iron lie angle digging the heel and shutting the clubface?

If your iron set is bent too upright for your physical posture and delivery mechanics, the heel of the club strikes the turf before the center of the face reaches the ball.

When the heel grabs the turf first, the ground acts as an anchor brake, twisting the hosel violently closed and causing heavy, low, pulled approach shots that miss 30 yards left of the green. Most golfers misdiagnose this as a swing flaw ('I pulled it'), when the sole was physically sabotaged by improper loft and lie tolerances.

Truth: Off-the-rack irons from retail shelves frequently vary by 2.0 degrees of lie angle right out of the box. An independent PGA blueprinter measures your dynamic lie on a launch monitor or impact board, bending the hosels on a digital Mitchell bending gauge so the entire sole contacts the turf flush.

When your irons are blueprint-calibrated to glide through the turf, the sharp leading edge stops digging into the ground—giving you the freedom to swing aggressively without the fear of a fat miss.
