Knot-

The Knot- is a putt and approach disc rated 4/3/-2/1. Two points of turn with a single point of fade suggest an understable putter flight, right drift at speed and only a soft ending for a right-hand backhand. It is not the mold for headwind work.

The minus sign is the point: Good Tree Disc Golf marks its stability variants with plus and minus, and its listing offers the Knot- as the complement to the Knot, straight-to-drifting at speed, straight with a small fade for slower arms. The PDGA approved it on 15 September 2025, seven weeks after the base Knot opened the New Hampshire brand's record.

TryDiscs records GT-1450, GT-660 and GT-660 Luminescence runs of the mold.
