MB101A Forged Iron

Feel, Stability, Workability

grindworks is proud to announce that Masters Champion and perennial world top 20 player Patrick Reed has chosen Japanese premium golf brand grindworks as his equipment of choice. This collaboration between Mr. Reed and grindworks not only involves Mr. Reed playing grindworks golf clubs but also partnering with grindworks on the development of new models and the growth of the brand.  

The MB-101A forged iron was developed together with Mr. Reed based on his needs as a top pro.   Mr. Reed approached grindworks on August, 2018 about creating iron that would allow him to knock down shots from any distance without worrying about ballooning or loss of direction.  Using soft S20C forging to enhance feel and spin, we created a stepped design for the Iron which places a focus on stability and control by raising the center of gravity height.  This allows Mr. Reed to attack the pin with a more penetrating shot and heavier spin resulting in shots closer the pin.

Mr. Reed put a prototype of the MB-101A into play in December 2019 at the Hero World Challenge and went on to win the World Golf Championships in Mexico in February with the irons.  In the short 2020 season, Mr. Reed had 1 victory and 6 top 10 finishes on the PGA Tour using the PR-101A and is currently ranked 8th in the world.

The MB-101A has a smallish head with less offset that frames the ball well at address. The sole is narrower and the leading edge is straighter but with relief which helps interact with the turf more cleanly at impact by minimizing fat shots/digging.  The stepped back muscle helps create a thinner top line which is more eye pleasing for the better player.  The stepped design also helps with functionality and feel, the thicker area is larger towards the toe which prevents the head from over rotating closed thus minimizing pulls and hooks.  The step groove in the middle makes the sweet spot slightly thinner, increasing spring effect and the widening the sweet spot of the face for more ball speeds and more forgiveness.

Premium S20C soft carbon steel forging and a finish in half satin NiCr plating results in a more pure feel and more bite on the ball. A mix of clean and modern aesthetics will appeal to a wide variety of golfers looking for an iron that focuses on feel, stability and shot making.

PR-202 Forged CNC Iron

Beauty in its simplicity, performance in its soul.

The all new grindworks PR-202 iron is a forged CNC cavity back with a primary focus on feel and performance. A simpler, no frills, back to basics design which gets the job done for more advanced players.

This year, grindworks released our new MB-101A/PR-101A muscle back which was designed in collaboration with Masters winner and perennial top 10 PGA pro Patrick Reed. The forged muscle back has succeeded in providing optimal feel, control and stability for Patrick during this season’s PGA Tour. The muscle back’s higher center of gravity provided a powerful trajectory at the pin which gives Patrick the control and stability to knock down shots in any condition.

However, Patrick and grindworks talked about creating an iron that was slightly more forgiving with a slightly higher trajectory for the 3 and 4 irons which usually are harder to launch and should have more of a focus on stable distance. grindworks founder Kiyonari Niimi began work on a cavity back that would provide that higher trajectory and ease of use while maintaining the feel and control of the muscle back.

A simple cavity design with a slightly thicker cavity area which helps lower the center of gravity matched with a compact, sharper head shape appeals to the better player.

One of Patrick’s concerns was that besides wanting a slightly higher trajectory he would sometimes want the flexibility of also using the longer irons for a punch shot or a stinger (lower trajectory shot). A punch shot can be hit with a slightly closed face to make up for the ball being placed further back in the stance. This type of shot is prone to going left since the face closed naturally faces left.

Countering the hook is not as simple as pushing the center of gravity towards the toe in an attempt to minimize over rotation but also focusing on the shape of the head as well as face progression/offset, toe and heel grind and more. We worked on creating an iron that not only had a stable center of gravity but a grind that allowed the iron to interact cleanly with the turf, keeping the head as square as possible at impact. We also increased the bounce as the set progresses and this helps preventing digging and fat shots equaling more pure and square impact. Less offset matched with a flatter lie prevent pulling the ball and preventing that over rotation.

The iron itself is a clean and simple design, premium forged from S20C steel, grinded by hand, the CNC machined and finished. In addition to the 3 and 4 irons we developed over 10 months, we decided to also add 5-PW for avid golfers to purchase as a set.

Already put into play by top pros on tour, the PR-202 has already been approved by the R&A as conforming to new groove rules.

PCX Iron

Pocket Cavity X - More distance, more forgiveness.

grindworks is proud to introduce the next level in performance irons, our new PCX iron – the Pocket Cavity X. The PCX iron is not only designed for stable distance performance but also tuned for sound and feel as well as visually appealing looks.

Pocket cavity irons have typically sacrificed feel and sound in order to achieve maximum distance and forgiveness. A combination of a pocket behind the cavity matched with a firmer face material can cause harder feel and more clicky sound that many golfers associate with these types of irons. grindworks placed equal importance for feel and sound when developing the PCX because we believe that ultimately the feel and sound translates into how the golfer perceives their impact, ie good or bad. We wanted to choose a face that would produce high spring effect and ball speeds but still be strong and feel good at impact. We settled on 17-PH Stainless for the face and placed a special polyurethane coated badge behind the face and inside the cavity. This combination provides a softer feel and more pleasing sound at impact.

We didn’t stop there either as the body of the iron will also affect the overall feel. We decided to use Nitronic 60, a grindworks signature high heat treated soft steel with a hardness level equivalent to S25C soft carbon steel. Not only does this contribute to feel and sound but also allows clubmakers to bend the loft and lies more easily.

In order to optimize spin we’ve made the PCX iron with 20 score lines compared to other irons which typically have 14-15 lines. This increases the amount of contact that grooves make with the ball to improve spin performance.

We understand how important sole and turf interaction is for making a good shot. We’ve implemented a D grind sole which provides more toe and heel and trailing edge relief which increases the versatility of the PCX iron in various lies. The less friction caused when your iron hits the ground before impact the better chance a player has of making square impact with the ball. This equals more ball speeds and better direction. The clean entry and exit also helps maintain the player’s swing speed through impact, generating maximum distance.  While grinding the sole like this is common for wedges it is rarely seen in irons.
