The name Proto Concept comes from the prototype-quality clubs that are developed for tour professionals, pushing the design boundaries, without the commercial  constraints of working to hit a target price point. Think of it like as a concept car. Conceptual prototypes aren’t produced with a mass-market mentality. Often, more advanced materials help mitigate traditional engineering trade-offs. For example, an iron that looks like a muscle-back at address but plays with the forgiveness of a game-improvement iron.

PROTO  CONCEPT C01

The Proto Concept C01 is a traditional muscle-back iron with a key difference. Because of the basic geometry of a blade iron, forgiveness is already constrained. To work around this limitation, Proto Concept impregnates the billet of S20C carbon steel with a round titanium rod. Complex. And more expensive.

Titanium is roughly 50-percent lighter than 1020 carbon steel. So, the titanium rod which weighs 25 grams saves 17 grams of weight. This discretionary weight is repositioned to allow for a deeper CG location and an overall footprint more akin to a cavity-back iron.

Because the titanium rod produces a slightly firmer feel at impact, Proto Concept uses the softer S20C carbon steel in 8-iron through PW and S25C in 5-iron through 7-iron. S25C is also used by ultra-luxury brands such as Miura.

The C01 shares the same lofts as other models in the Proto Concept range.

C03TC

The Proto Concept C03TC iron is forged from the same S25C soft carbon steel as the C01.

Crafted with unparalleled ultra-precision. A tour cavity back evolved through a centre of gravity designed for each club number.

While succeeding the functionality of the previous C03 model which was already close to perfection as a soft iron integrated cavity back iron, the centre of gravity design was developed for each club number through using 3D CAD. The C03TC was crafted to become a world-standard soft iron forged iron with enhanced balance as a set, pursuing functionality for each club number in response to feedback received at U.S. tours.

The C03 shares the same lofts as other models in the Proto Concept range.

C05

Tour pocket cavity iron with enhanced distance and straight-line performance.

 The C05 irons use two different materials to construct the clubhead. The body is forged from S20C soft carbon steel while the face uses a thinner, more flexible piece of forged SAE8655 chrome molybdenum steel. The face is then precision welded onto the body. With that, the primary benefit of the paper-thin face is the ability to generate higher ball speeds, and therefore more distance, for players who need it. In addition, both the C05 and C07 have a milled pocket-cavity throughout the set to reposition weight low and around the perimeter of the clubhead.

Typically, face-welding creates an impact sensation that is quite different from a single-piece forged iron. This is where Endo has a manufacturing advantage. In the Proto Concept C05 iron, the face varies between 2.4 mm and 2.7 mm in thickness to generate a balance of distance and feel.

07

Pocket cavity iron with satisfying feel that prioritizes distance and softness.

The C07 irons use two different materials to construct the clubhead. The body is forged from S20C soft carbon steel while the face uses a thinner, more flexible piece of forged SAE8655 chrome molybdenum steel. The face is then precision welded onto the body. With that, the primary benefit of the paper-thin face is the ability to generate higher ball speeds, and therefore more distance, for players who need it. In addition, both the C07 has a milled pocket-cavity throughout the set to reposition weight low and around the perimeter of the clubhead.

Typically, face-welding creates an impact sensation that is quite different from a single-piece forged iron. And, yes, in this case, different = undesirable. Again, this is where Endo has a manufacturing advantage. In the Proto Concept C07 iron, Endo created a face with three discrete face thickness regions—2.7 mm, 2.3mm, and 1.8 mm. 

The C07 shares the same lofts as other models in the Proto Concept range.

Clubs for amateurs. Chosen by tour pros.

During the 2022 season, PROTOCONCEPT displayed great success on the professional tour stage, particularly on the US LPGA Tour. Lydia Ko, who has regained her No. 1 spot on the world rankings with three wins and four championships in a season, is one of the many players who have chosen our products and put them to use in tours.

Lydia Ko is renowned for in depth testing of her golf equipment to optimise her bag.  During iron testing Lydia narrowed her choice down to Mizuno, Srixon, and Proto Concept.

Proto Concept irons won with consistently tighter dispersion and carry yardages.
