The Viking Discs Knife is a stable putt and approach disc built to take more power than most putters. At 2 / 3 / 0 / 2, the zero turn and two fade describe a disc that holds the angle you release it on and finishes left, rather than one that flips when you throw it hard.
Two speed and three glide keep the flight slow and low, so it lands near where it fades instead of skidding past. Viking shapes the rim for both power and fan grip and pitches it as comfortable from the tee as well as on short approaches. A faster arm gets the straight portion of the flight; at lower power the fade arrives sooner and the flight is shorter, but the shape is the same. Infinite reviewer averages land near 2.8 / 3.1 / 0 / 1.8, which is slightly less fade than the rating and fits the way it is usually described — dependably stable rather than a true utility putter.
That puts it in the approach slot more than the putting slot. It takes a hyzer without flattening out and handles a headwind better than a neutral putter will. Reviewers who have thrown it alongside other approach putters put it in the same role as a Discraft Zone but slower, and straighter than a Westside Harp. On longer putts the two fade is something you aim around.
Viking Discs is a Finnish manufacturer and names its lineup after Norse figures and imagery throughout, though it does not publish a reason for any individual name. The Knife was PDGA approved in December 2016, among the brand’s earliest molds. It comes in Ground, Storm and Armor — Ground the grippy base plastic, Storm the stiff durable premium line, Armor the flexible all-rounder. Reviewers note the flight plate flattens out as it beats in.
How much the Knife turns and fades depends on how hard it is thrown. These three shapes are drawn from the manufacturer’s numbers, not from measured throws.
Measured by the PDGA when the Knife was certified. Each card names discs that share the number, so you can feel it in the hand.
