The classic 001 blade shape with true zero torque balance
Sub 70 Golf · PuttersThe 001Z takes Sub 70's classic 001 blade profile and rebalances it with true zero torque technology, so the face wants to stay square through the stroke. It keeps the compact, clean look of a traditional blade while cutting down the open-and-close rotation blades normally allow. The head is CNC milled from soft 1045 carbon steel and was co-designed with Joel Pera of Just a Potamus Golf.

Why golfers choose it
Engineered so the face resists rotating open and closed, helping you start more putts on your intended line.
The traditional 001 profile keeps the clean, compact appearance accomplished players prefer, without a mallet footprint.
Developed with Joel Pera of Just a Potamus Golf, a custom builder known for precision weighting and balance work.

The 001Z suits golfers who like a compact blade at address but have trouble returning the face square consistently. Because the zero torque design keeps the face stable rather than letting it swing open and closed, it pairs best with players who want the putter, not their hands, to manage face angle. It is available right- and left-handed.
