Where the face
meets the ball.
Sweet Touch is a mechanical putting trainer. It guides the putter to a repeatable height and path behind the ball, so contact happens close to the center of the face — with no electronics, no batteries and nothing attached to your putter.
The blind spot
You can see the line. You can see the result. What you can't see is the moment in between — how high the face was traveling, and where on it the ball actually made contact.
01 · Address — face height
02 · Impact — height varies
03 · Address — alignment
04 · Impact — contact point
The center of a putter face sits roughly 13 mm off the ground. The center of a golf ball sits roughly 21.35 mm. Sweet Touch is built around that gap: it encourages the putter to travel slightly above the turf so the face meets the ball nearer its center, instead of striking low with the top of the face.
A passage,
not a line
A base member sits behind the ball. Side and upper guides form a passage the putter head travels through, limiting deviation in two axes at once. The feedback comes from the structure itself — there is nothing to read, calibrate or charge.
Two axes, one passage
The head travels through a defined space rather than alongside a printed line, limiting vertical and lateral deviation together.
2 mm increments
Modular plates tune the passage height to your putter and your stroke, then stay put so the same setup repeats session to session.
Repositionable
Moves for right- and left-handed use, and extends to accommodate mallet heads and wider putter profiles.
Tees for real greens
Standard tees fix the unit to the surface, so practice isn't limited to an indoor mat.
Your putter stays your putter
Nothing clamps to the head or shaft. You practice with the same club, the same weight and the same feel you play with.
Progressive training
The guides come off. Start with the passage wide and learn the height, then narrow it as the stroke settles. Three configurations, one base.
Base only
The base member alone. The putter passes over it freely — the only thing being trained is how high the face travels through impact.
Tuned in 2 mm steps
Loft, lie and stroke type all change the height the face wants to travel at. Stackable plates let you find yours and keep it.
Practice where you play
Two anchor holes take standard tees, so the unit stays where you set it on a real green — not only on an indoor mat.
Finish
Matte body, machined guide surfaces, an engraved mark. The detail is where a training aid either earns a place in the bag or doesn't.

Built by a coach
Sweet Touch started on a lesson tee, not a drawing board. The problem was described by students long before it was patented.
Ten years coaching at golf clubs in China, then a decade of teaching juniors and club players back in Korea. The same fault kept showing up on the putting green: a face striking low and off-center, invisible to the player making the stroke.
He modelled the first version himself in CAD, printed it, broke it, and printed it again. The registered patents, the trademarks, the export paperwork and the prototypes all carry the same signature.
Sweet Touch is designed by a TPI Certified Professional. It is not affiliated with, endorsed or certified by the Titleist Performance Institute.

Overseas patent filings total six: one PCT international application (filing period closed) and five national-phase applications — United States, Japan, China, Hong Kong and the European Patent Office — currently under examination. Four domestic patent applications have been filed in total, of which two are registered and two remain under examination. The SMART5 Rights grade A (top 12.3%) refers specifically to KR 10-2588730 and reflects the sub-category benchmark used in that evaluation.
