Paradox Putters?

Breakthrough Golf Technology (BGT), the folks renowned for their game-changing Stability putter shafts, have upped the ante. Meet their latest creation: the Paradox putter line. This isn’t just another entry into the torque-free putter club—BGT says they’ve gone a step further. They’re making some bold promises with this release, and we’re here to break down what they’ve brought to the table in a way that won’t leave you scratching your head.

Big Claims, Big Game

BGT isn’t shy about hyping up the Paradox putters. Here’s what they’re touting:

• More putts finding the bottom of the cup.

• Missed putts landing 10% closer to the hole.

• A pure roll kicking in 20% faster than the competition.

Lofty? Sure. But if they’re onto something, it could shake up the putting game.

The Putters:

For their debut, BGT offers two flavors: a mallet and a blade. Both sport a distinctive slanted look and a unique two-tone finish, thanks to the mix of materials in their construction. The blade feels familiar at address—think classic design with a slight onset—but the material contrast doubles as an alignment aid, paired with a handy center mark. The mallet, on the other hand, channels a #7 or Phantom vibe with a beefier footprint, more onset, and likely a higher moment of inertia (MOI) for extra forgiveness. They’re eye-catching, no doubt, and built with purpose.

The Tech:

BGT calls their secret sauce “Principal Axis Technology,” a twist on the zero-torque concept. The gist? They’ve tweaked the putter’s principal axis of inertia—the imaginary line tied to how mass is distributed—to sync up with your putting stroke. How’d they do it? By loading weight high in the toe and low in the heel relative to the ground. We’ll skip the calculus (you’re welcome) and cut to the chase with a quick visual.

Picture a standard zero-torque putter at address: its center of gravity (CG) sits dead center, with the shaft axis running right through it. The inertial axes are typically square to the ground. BGT’s twist shifts that setup—adding weight high in the toe and low in the heel tilts the vertical inertial axis closer to the shaft’s angle, narrowing the gap between them. Their pitch? “This precise alignment optimizes dynamic performance throughout the stroke and keeps the putter square. Paradox is the only putter that adjusts to you, not the other way around—the only one that fights to stay square,” says BGT.

Does It Actually Work?

Here’s where we put on our skeptic hats. After crunching some numbers, we’re not entirely sold that BGT’s design delivers a night-and-day difference from a solid zero-torque putter. Both setups run the shaft through the CG, meaning no twisty feedback in your hands and, in theory, a face that stays square through the stroke. For the putter to “fight to stay square,” it’d need to generate its own corrective force from the player’s swing energy. Our math doesn’t see that happening—at least not based on the theory as we’ve pieced it together.

Zero torque is zero torque; it doesn’t get “more zero.” Blindfolded, we’d wager most players couldn’t tell the two apart. That said, the concept has a certain logic—tilting that inertial axis might offer a subtle edge in stability we can’t fully dismiss without testing. Independent reviews and lab data will be the real judges here. For now, we’re intrigued by the Paradox line and can’t wait to get our hands on one once it hits the market.
