What you need to know: In January 2022, in the name of creating a blades with the MOI of mallets and forward CG, Odyssey threw everything at the wall with the Tri-Hot 5K family of blade putters: stainless steel, tungsten, 6061 aircraft grade aluminum. A year later, the company is bringing the same technology package to mallets with the Rossie and Seven models. The Tri-Hot 5K lineup now stands at seven putters (four with multiple necks).

2023 Odyssey Tri-Hot putters: Features and technology

Engineers applied the “Tri-Hot formula” utilized in blade putters in 2022 to move CG forward and raise MOI for a more forgiving mallet design — and a 5,000 IZZ inertia level (hence “5K”). Golfers will see improved speed and spin control, as well as consistency on off-center hits, according to the company, resulting in golf balls that finish closer to the hole when sub-optimally struck.

Stainless steel front: Odyssey touts the side-spin reducing capabilities of the 303 stainless steel hosel and face area for off-center putts. Tighter dispersion and putts that a more likely to go in results. Acting in a complementary fashion, the rear of the mallets are milled for tighter shape and weight tolerances that allows the CG to remain forward.

Tungsten front weights: Up to 120 grams of tungsten is positioned behind the face in the heel and toe sections of the putter heads. The resulting forward CG improves roll and increases inertia.

Interchangeable front weights: Available in 5, 10, 15 and 20 grams to dial in head weight and performance.

White Hot insert: 2023 Tri-Hot 5K putters add the iconic two-part urethane White Hot insert, which was originally developed using the same material as Callaway’s Rule 35 golf ball. White Hot, with its “firm but soft” properties has been a long-time favorite of Callaway staffers and recreational golfers. According to Callaway, “They’ve been asking for us to bring these technologies back and we’ve listened.” Can’t argue with that.

Stroke Lab shaft: The newest generation of Callaway’s multi-material Stroke Lab shaft features a shortened steel section and reduced weight (seven grams). Additionally it is stiffer. All of this leads to more stability and consistency.

Additional model details

Full lineup details — and who they’re for — including 2022 releases, via Callaway. 

One: A classically shaped heel toe weighted putter with a crank neck hosel creating moderate toe hang making it suitable for strokes that have moderate arc and face rotation

Two: A classically shaped heel toe weighted putter with a crank neck hosel creating moderate toe hang making it suitable for strokes that have moderate arc and face rotation. Less rounded than the One.

Three: A classically shaped heel toe weighted putter with a flow neck hosel yielding more toe hang making it suitable for strokes with more aggressive swing arc and face rotation

Double Wide (CH, CB): CH: A wide blade with a crank neck hosel yielding moderate toe hang making it suitable for strokes with moderate swing arc and face rotation. CS: Face-balanced center shafted wide blade making it suitable for strokes with minimal swing arc and face rotation

Triple Wide (DB, CS): DB: A face-balanced double bend wide blade making it suitable for strokes with minimal swing arc and face rotation. CS: A face-balanced center shafted wide blade making it suitable for strokes with minimal swing arc and face rotation.

Rossie: (DB, S): DB: A face-balanced double bend mallet suitable for strokes with minimal arc and face rotation. S: A mallet with a short slant hosel, suitable for strokes with arc and face rotation.

Seven (DB, S, CH): DB: A face-balanced double bend mallet suitable for strokes with minimal arc and face rotation. S:  mallet with a short slant hosel, suitable for strokes with arc and face rotation. CH: a mallet with a crank hosel, suitable for strokes with moderate arc and face rotation.
