TeI3

The TeI3 line begins in 1997, and the record holds three distinct entries from that single year: the Teryllium 2 edition, the Teryllium edition, and what the record lists as the First Generation. Drivingrangeheroes.com's account of that first generation ties it directly to Tiger Woods, calling it Tiger's 1997 Masters putter, the first generation with the flush Teryllium insert and TeI3 sole stamp. Youtube.com, describing the same 1997 putter, calls it made legendary by Tiger Woods' 1997 Masters victory, and points to a Teryllium insert 3, 12 metal alloy insert backed by an elastomer membrane, while drivingrangeheroes.com separately describes the inserts of that first run as shiny coppery. On the back, youtube.com notes iconic white dots on the back from the elastomer membrane. Reviewers were taken with the early putters on sight and in hand: drivingrangeheroes.com called them not just beautiful, but they felt amazing too, and warned that finding one in good condition on eBay means expecting big dollars.

The stamp itself moved over the line's early years. Youtube.com reports that Scotty started stamping the face with a TI3 after the Masters win for more visibility and uniqueness, a shift the record captures in both the early face-stamped version and the separately listed Face Stamp Generation, with drivingrangeheroes.com describing each as the TeI3 stamp moved to the face of the putter. A later manufacturing change reshaped the insert again: drivingrangeheroes.com attributes the final generation's white elastomer ring to a change in milling houses where they had a hard time getting the tolerances of the insert and cutout on the face correct, a fix the outlet frames as addressing a spacing and tolerance issue rather than a cosmetic choice. The general Teryllium TeI3 entry adds further texture from golf.com, including a domino pattern in the cavity, 32 holes drilled into the back cavity, and the detail that Cameron was 32 years old when he created the TeI3 for Woods; golf.com also notes GE Tub and Tile Silicone used to eliminate harsh feel.

Along the way the record holds variants like the Sole Stamp Teryllium, which 2ndswing.com describes as TeI3 stamped on sole and without the white border surrounding the Teryllium on the face, distinguishing it from newer Teryllium putters that feature TeI3 stamping on the face and white border, and the TeI3 Buttonback, which golf.com notes features three screws in the cavity. A personal edition, the Teryllium 1.5, carries its own story: golf.com reports it was used from 8th grade into high school, won 2009 U.S. Junior Amateur Championship, in a chrome finish with a short flow neck, and golf.com's broader piece on the player says he was draining putts with his Teryllium 1.5 putter.

The line resurfaces decades later with the T22, released in 2022. Golf.com describes it as an updated version of the putter created to celebrate its anniversary, most recently the T22, and elsewhere as created to celebrate the TeI3's anniversary, while drivingrangeheroes.com frames it as an updated limited version of the classic Teryllium putter line with a few modern twists. Golf.com's broader note on the original run observes that the original Teryllium continues to have a cult following with gearheads, a claim that sits comfortably alongside the eleven releases the record has gathered under the TeI3 name.
