Hand-cast in Colorado.\u003c\/p\u003e\n\u003cp\u003eOne-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.\u003c\/p\u003e\n\u003cp\u003eYou 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.\u003c\/p\u003e\n\u003ch3\u003eHow you use it\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eHold it flat against the face of your iron.

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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill it scratch my club?\u003c\/strong\u003e\u003cbr\u003eNo. The contact surface is the cast urethane back, not the magnets. After 50+ test rounds across multiple irons in development, no scratching reported.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow strong is the hold?\u003c\/strong\u003e\u003cbr\u003eStrong 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs it legal for tournament play?\u003c\/strong\u003e\u003cbr\u003eIt'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.\u003c\/p\u003e","brand":"One Club Ninja","offers":[{"title":"Green \/ Right-Handed","offer_id":47389300392114,"sku":"OCN-PA-01-GRN","price":49.0,"currency_code":"USD","in_stock":true},{"title":"Light Gray \/ Right-Handed","offer_id":47389300424882,"sku":"OCN-PA-01-LGR","price":49.0,"currency_code":"USD","in_stock":true},{"title":"Obsidian \/ Right-Handed","offer_id":47389300457650,"sku":"OCN-PA-01-OBS","price":49.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/5131\/7938\/files\/PXL_20260504_211239961-EDIT.jpg?v=1777932009","url":"https:\/\/shop.oneclubninja.com\/products\/putter-attachment","provider":"One Club Ninja","version":"1.0","type":"link"}
