One iron. All the way to the cup.
A magnetic putter face that snaps onto your iron in seconds, so you can putt with the same club you hit all round. Hand-cast in Colorado.
One-club golf is one iron, a sleeve of balls, and a few hours on a par 3 or executive course. No fourteen-club bag, no club selection on every shot. The one shot it never handled well was the putt: a 30-degree iron face launches a ball, it doesn't roll one. This is the piece that finishes the round.
You walk up to your ball on the green, hold the attachment flat against the face of your iron, and the magnets pull it into place. A short slide to set alignment and the club in your hand has a flat putter face. You putt, pull it off, and walk to the next tee. The whole sequence takes a few seconds.
How you use it
- Wipe the back clean, then hold it flat against the face of your iron. The magnets pull it into place.
- Putt. Pendulum stroke, choke down if you want, roll it in.
- Pull it straight off and drop it in your pocket or waist bag.

FAQ
What is one-club golf?
A full round with a single club, usually a 7-iron, for tee shots, approaches, chips, and putts. Most often played on par 3 or executive courses. It's not a gimmick. People have played this way for decades, and it usually moves faster than a full-bag group.
Will it scratch my club?
No. The magnets are recessed and never touch your club. Just wipe the back (the side with the magnets) clean before attaching so trapped dirt doesn't scratch.
How strong is the hold?
Strong enough that you feel it pull into place. It does not wobble, slide, or fall off during a normal putting stroke, and comes off cleanly when you pull it straight off.
Is it legal for tournament play?
It's not USGA-conforming for competition. For casual rounds, par 3 courses, executive courses, and one-club golf, no one's stopping you. For a USGA-rated event, use a real putter.
