King 3DP

The Cobra King 3DP line covers six releases: the base King 3DP Putters, the Grandsport-35 and its Armlock companion, the Supernova, and the Agera and its own Armlock companion. Across the line the shape names split into two families of stroke fit, at least according to tgw.com's descriptions, with the Agera and Supernova reported as suited to a straight-back, straight-through stroke and paired with a face-balanced single bend hosel, while the Grandsport-35 is reported with a plumbers neck hosel and a 35 degree toe hang, aimed instead at golfers carrying a slight arc. The Armlock editions of both the Grandsport-35 and Agera carry the same neck types as their standard counterparts, per tgw.com, distinguished mainly by the longer, armlock-length build.

What ties the six together is the construction reported for the line's base entry: a stainless steel body under an aluminum cap, with an aluminum face insert milled with four flat surfaces, finished in black and silver. tgw.com described this as multi-material construction, and it's the shared foundation the individual head shapes build on rather than a spec unique to any one release.

On how they play, the opinions on record point in the same direction without adding much daylight between them. tgw.com's review called the putters extremely solid and stable, and a broader community note echoes that same read, adding that the high moi is seen as reducing loss on mis-hits and that the descending loft technology is credited with producing a consistent roll. Both are opinions, not house findings, but they agree with each other where the line is concerned, for whatever that consensus is worth to a reader sorting through six similarly built heads with two different stroke intentions behind them.
