1-A

The 1-A sits at the front of Ping's putter history, described by vkgolfshop.com as a design that dates to the 1950s. That same source calls out the trademark hollow design, and points to straight lines for alignment paired with heel-toe weighting for balance as the working idea behind the head.

On material, vkgolfshop.com lists the head as high tensile manganese bronze, finished mar-resistant and satin. The site also gives a weight of 1.101 KG and a dimension listing of 220 cm (Length) x 210 cm (Width) x 200 cm (Height), along with an MSRP of 2649.00 RM. These figures come from that single retailer listing rather than from Ping directly, and should be read with that in mind.

Community opinion on the 1-A leans favorable. One assessment credits it with a reliable sweetspot and better accuracy, while vkgolfshop.com's own editorial framing goes further, calling the 1A revolutionary in the 1950s and crediting it with instantly improving many golfers' games through that same sweetspot reliability and accuracy gain. Both readings point in the same direction, praise for the heel-toe balancing and alignment approach, though neither is offered here as more than the view of the source that made it.
