“Cobra's 3D-printed Nova/SuperNova, a big alignment-heavy metal-lattice mallet; face-balanced for a straight stroke and very stable. Bold looks and high forgiveness.”

The 2021 King Supernova was the fang-shaped member of Cobra's first full 3D-printed putter line. Its steel frame surrounded a light nylon lattice and aluminum cap, allowing 42 grams of tungsten to sit around the perimeter of the oversized head. A single-bend shaft made the base Supernova face-balanced, and broad rails plus a central line supplied strong directional references. Cobra paired that stable chassis with SIK's aluminum Descending Loft face, whose four zones change from 4 degrees at the top to 1 degree at the bottom to manage launch across different strike and delivery patterns.

The Supernova is a recognizable early retail application of 3D printing in a high-MOI mallet, but it was a normal production model and later generations dilute scarcity-driven appeal.

Best for a low-rotation or straight-back, straight-through stroke that benefits from a face-balanced mallet and prominent alignment. Golfers who release a toe-hanging head aggressively may find it reluctant to rotate.

• The period catalog identifies the base Supernova as an oversized fang with a single-bend shaft and zero-degree toe hang.
• Its construction uses a 3D-printed nylon insert, steel frame, aluminum cap and 42 grams of perimeter tungsten.
• The SIK aluminum face has four descending lofts of 4, 3, 2 and 1 degrees.
• Cobra offered the original head in right- and left-handed builds and at 33, 34 and 35 inches, with regional qualifications on the 33-inch stock option.
• Contemporary testing described a muted, soft strike and strong alignment assistance from the wing rails.

Cobra's 2021 family followed its limited Supersport-35 and showed how additive manufacturing could become a repeatable internal structure rather than a novelty finish. The Supernova translated that idea into the familiar fang-mallet category.

Current 2nd Swing asks observed in July 2026 were roughly $112-$154, and Callaway's July 2026 trade card listed $99. Verify that a listing is the base 2021 single-bend head, not a -20, -30 or later-generation Supernova.
