The Two-Knuckle Grip Test That Can Tame Your Slice
By Staff Writer

Key takeaways
- Seeing fewer than two knuckles on your lead hand at address signals an open clubface and a slice-prone setup.
- Clubface angle at impact accounts for roughly 75% to 85% of a shot's initial direction, according to launch-monitor data.
- A stronger grip alone won't fix an outside-in swing path — it can turn a slice into a low pull-hook instead.
- Standard round or ribbed grips are conforming under the Rules of Golf; molded training grips are not legal for competition.
What does the two-knuckle grip test check?
Take your normal setup and look straight down at your lead hand without tilting your head. Right-handed players should see at least two knuckles on that hand. Fewer than two means the grip has preset an open clubface before the swing even starts, a common root cause of a weak, high slice.
Why does the grip matter this much?
The hands are the only connection between the golfer and the club, transmitting all of the club's rotational torque and face orientation through a small contact area. Launch-monitor data shows clubface angle at impact drives roughly 75% to 85% of a shot's initial direction, which is why a couple of degrees of open face at address can outweigh almost anything else in the swing.
A two-knuckle grip fixes the face. Only the swing path fixes the miss.
What a grip change won't do
Strengthening the grip closes the clubface, but it doesn't correct a swing path that travels from outside to inside across the ball. Paired together, a stronger grip and an out-to-in path can turn a banana slice into a low, sharp pull-hook. Fixing curvature for good means addressing face and path separately, through both grip and swing-path work.
What about grip pressure?
Many amateurs hold the club far too tightly, which restricts the wrists from hinging and releasing freely through impact. A lighter, steadier pressure throughout the swing allows for a fuller release and more speed than a death grip does.
Are training grips legal for competition?
Under the USGA and R&A Equipment Rules, standard round or ribbed grips are conforming. Grips with molded finger channels or thumb indentations, often sold as training aids, are not conforming and can't be used in a competitive round — practice with them on the range only.
Frequently asked questions
How many knuckles should you see in a golf grip?
A right-handed golfer should see at least two knuckles on the lead hand at address; seeing zero or one usually signals a weak, open-face grip.
Will a stronger grip fix my slice?
It can reduce slice spin by closing the clubface, but it won't correct an outside-in swing path on its own and may turn a slice into a hook.
Are molded training grips legal in tournaments?
No. Grips with pre-molded finger or thumb indentations are non-conforming under the Rules of Golf and can't be used in competitive rounds.
