GolfWRX Insider: The real story of Tiger’s Titleist 681T irons
The speculation around these irons (and every Tiger Woods iron thereafter) has been just shy of comical. Anything from “Mizunos stamped with different OEM logos” to “Miura secretly forging them in a cave full of kryptonite and fairy dust.”
It’s all entertaining, but in the end, a good conspiracy theory is typically just that: a theory.
I thought it was a good time to set the record straight—beyond doing it on my podcast over a year ago—with the man who was in the middle of it: Larry Bobka, VP of Golf Club Promotion during that time.
JW: How did the process begin, and specifically what was Tiger looking for?
LB: I was just finishing up my project with Davis and was asked if I could lend a hand with Tiger. Terry McCabe, VP of R&D, had few prototypes going, so there had been some conversations with Tiger before me. I went down to Isleworth, met with Butch and Tiger, and we discussed his current set…what he liked, didn’t like, and what would make a Titleist set better.
JW: What inspirations did you take from older clubs and how much did the design of his Mizuno irons influence the design?
LB: Having worked with players at Wilson (mentored by Bob Mendralla), I felt confident that we could make him a great set of clubs. His Mizuno set was important from a standpoint of watching ball flight and turf interaction. They make really good irons. Tiger had sent me a set of old Hogan Apex 1973 irons, as well, that had a lot more camber in the sole. I added a bit more…one of the tweaks added to the 681 forgings.
JW: How many different prototypes were made until you landed on the 681?
LB: Terry had made Tiger a couple of 5-iron prototypes. I left Isleworth with a simple plan: make Tiger three identical sets and let him choose the best 2, 3, 4-iron, etc. down through the bag—old school club making I learned from Bob Mendrella
JW: Like his P7TW, the 681 had a phase 1 that he put into play. The 1998/1999 model was a touch different than the 681, can you explain those a bit?
LB: His original sets were made from old Titleist forgings made by Hoffman Products (McCabe Design pictured below) and some blank forgings from Endo. After he liked the irons, we tooled up the 681’s at Endo.
JW: How much bounce did he like in his irons?
LB: If you look at the stock 681’s, they have a fair amount of bounce. His long irons are weaker than standard loft, which gave him more bounce in the 2- 5-irons.
JW: What older Titleist blades closest resemble the Tiger Iron?
LB: Titleist Tour Model (Box Blade). That’s what inspired his 5-PW.
JW: What was testing like—with no launch data?
LB: Old school club making. As Toney Penna told me once: look, listen, and copy—look at ball flight, turf interaction, listen to what the player says and doesn’t say, copy what’s in your head. We did have the Titleist Launch Monitor later when he came to Oceanside just confirm ball flight.
JW: Once and for all, who forged the Tiger Titleist irons?
LB: We did in Carlsbad from Hoffman and Endo forgings. Miura made a limited edition (pictured below) for Titleist Japan, but he never used them.
JW: Did he ever consider cavity backs at all?
LB: No, he hit Davis’ cavity forgings (below) a couple of times on the range at events.

We always get some great photos of some phenomenal putters at tour events and love to share them. Here are a few from the 2024 Zurich Classic that caught our eye and seemed interesting. (And as a reminder, you can check out all our photos from New Orleans here)
MJ Daffue’s Scotty Cameron T-11 Prototype
MJ is going with the new Scotty Cameron T-11 Prototype this week. The putter is a multi-piece mallet that puts an emphasis on stability with the wings on the back. Daffue’s putter does have a design that differs from retail with a monotone finish, which eliminates the black paint on the aluminum parts that we see at retail. He also has a half siteline milled into the top and an L-neck welded on for some additional toe hang. The face features a deeper milling that should offer a softer feel and slightly quieter sound.
Scotty Cameron T-7.5 Prototype
We spotted a few different Scotty Cameron Phantom models with modified rear flanges. It looks like the straight black flange was cut into a half circle for a little softer look at address. On this T-7.5, you can still see the raw aluminum from the back view, so this might have been a last-minute job to get them out on tour. The semi-circle also has a white line on it, maybe to frame the ball differently.
Alex Fitzpatrick’s Bettinardi SS16 DASS
Alex’s SS16 is made from Bettinardi’s famous D.A.S.S., or double-aged stainless steel, for a softer and more responsive feel. The face has a unique diamond pattern milling and features a logo that I feel like I have seen before, but can’t put a name to. The putter is a classic mid-mallet style with a simple, single white siteline on the top. The sole is clean with just the SS16, DASS, and a green triangle logo on it.
Steve Stricker’s Odyssey White Hot No. 2
This putter has made some amazing putts in its long career! Stricker’s White Hot No. 2 might be in the top 10 of most famous putters in golf. When you see all the dents and lead tape, you know the heel will be up and it will be sinking putts! The soft White Hot insert looks to be in good shape and has less wear on it than the rest of the putter. We don’t know how much lead tape is on the sole, but it has to be multiple layers compacted down over the years.
Doug Ghim’s Scotty Cameron T-7 Prototype
This T-7 should win the award for “best color finish” in this list with its deep chromatic bronze. It looks like Scotty added a cherry bomb dot to the heel of the deep-milled face and filled it with a very dark blue paint. The rest of the putter looks pretty stock with its single site line on the topline and twin site lines down the “fangs” of the putter. Twin 5-gram weights are installed in the sole and the putter is finished off with a gloss black double bend shaft with a fill shaft offset.

Project X’s Denali wood shafts have been seen in more and more golf bags this year as we start off the season. As a refresher, Denali Blue is the mid-launch and mid-spin model while Denali Black is for players seeking lower launch and spin.
Denali combines great feel with stability and increased ball speed. Currently, Project X only offers Denali Blue and Black in wood shafts, but we spotted a hybrid shaft in Daniel Berger’s bag at the 2024 Zurich Classic.
The shaft looks to be a Denali Blue 105G – HY in TX flex. No word on details from Project X yet but we can assume that this is a mid-launching shaft that weighs around 105 grams in Tour X-Stiff flex.
Berger has this shaft in his TaylorMade P770 3-iron, likely for some added launch and spin to hold the green from longer distances.
Hopefully, this means we will see some more shafts coming under the Denali name in the future, as I think many of us would like to try one in a hybrid or utility iron!

So who made the production 681’s? Endo? I’ve got some Custom Grinds that I rather enjoy.

Looking at the lofts he is playing, they are the same loft set up that guys on tour are still playing. Just will different numbers stamped on the heads.

Titleist put out some beauties in early 2000’s. They had Phil 731pm, 681,690,680’s. Not bad when your staff was Tiger, Phil, Duval, Love, Adam Scott, and Ernie Els.

Ummm yeah. Can we get the next topic on those Davis cavity backs, never heard of nor seen those. Where they been my whole life? Titleist put out some sneaky good iron sets for Phil (Titleist PM731) and Tiger in early 2000’s. At one point they had Tiger, Phil, Ernie, Davis, Duval all gaming their irons and winning tournaments.

I’m pretty sure it’s been known / suspected for a while tigers irons were endo forgings. Miura does some other guys but tiger was always endo. What makes the debate pointless though is 99.9999999% of golfers couldn’t tell the difference between an iron forged by Miura v the same iron shape cast by some back yard club maker. I really think people just don’t grasp the level of feel the worlds best have. We are not the worlds best

He closed his doors in early 2000’s. Made some great irons over the years though. Scratch were the last guys to do something similar in USA.
