Carlton Matsui using KYOEI forgings.

Miura does not Forge their own heads or finish their own heads. I've been saying this for a decade. TADA mfg does their forging and Kyoshin does their finishing. They are 2 piece spin welded heads. The reason is not tolerance but it is price. making a 2-D mold ( spin welded ) is far cheaper than a 3-D mold. They are not the only ones who do this. Shin-Nihon also does spin welded. I've been to Tada mfg and they have told me in person they forge for Miura. I also have their business registration for their foundry that shows Miura does not own it although they have said so in the past. Tada mfg uses a small press. ENDO on the other hand is a legit foundry. I would not even consider the two in the same class. Keep in mind we pretty much created the new EPON, they still use the logo and model naming we created for them in 2005/2006. They use giant Enamoto presses and they have so many capabilities that Miura will never have, this press would not even fit in the Miura factory. FYI - I have designed for both companies. Keep in mind we no longer sell both brands. I have no bias and think both companies are watered down and lack soul. club masters who carve molds can spot the difference visually with 2 piece forgings. Its rather snobby but across the board I can tell you that if you take 1 piece vs 2 piece in the EXACT same design 1 piece will tend to feel softer. I believe both Titlist and Taylormade stopped using Miura once they figured out the heads were spin welded. Also worth noting is that Endo does not grind they are mold/polish, Miura kinda does but it's mostly polishing to shape. KYOEI grinds. Here is my bias - KYOEI. They forge, grind, finish and do all steps in house. Epon and ENDO are not capable of all steps in house. While KYOEI is the least powerful due to management they are the true history of club forging in Japan. I dont like when people say Miura Forged or Fujimoto Forged because neither of them actually forge. All that garble I just said doesn't really matter, thats just insider info. So much falls in the hands of the player and their preference and specs, design, shaft etc..

Awesome blades and cult driver. If you ever need a refinish let me know.

PINGs are easy to love thats why 🙂

Feel depends on so much, shaft grip, ball, temps. Club design, bounce and loft too.

stunners stew!

hi blake! cb is on the demanding side, has a hint of offset. fit and finish (polishing) on these is a hair better than Miura and Epon. Oichi forgings sent to Shinagawas son for the grind. Kyoshin finished (same as miura ) but extra step of niigata polishing. You can get custom finishes, combo set too! we know them well.

There is confusion about where the latest models are made. I'm not 100% myself. I think the 1 piece models are still made in Japan or at least partly made in Japan. But if this was the case they could still keep custom grinds and stamping alive. So maybe it was just a pain in the ass to keep this custom dept open with such little sales. Mizuno has changed their distribution model a lot recently, focusing on Mizuno Pro dealers and big box stores. We can't get the pro series. As skyline has said all the new Mizuno Pro models are part of Yoro but not offering grinds and stamping adjustments.

Yoro now means custom shafts and build specs, and in some models custom finish. Before when Yoro was only made of the hand made models it was for custom finish, stamp, and grinds. Majority of Mizuno irons are made in China now. No they are done. not sold anymore.

I don't want people to mix up Iron content with carbon content. 1025 Steel has Iron content of 99.03-99.48% FE is within the same range of Iron content but has a lower carbon content. FE steel's main selling point is not for the consumer. It's for the factory or foundry. Lower carbon = softer metal = the ability to use a small 800ton press to forge it. S-15C steel with low heat treatment is useless in golf. S15C with high heat treatment is the same as S-25C with lower heat treatment with a higher pressure machine. The most stable material is JIS S25C. Take an FE steel iron to a range with matt's. In no time the lie's and loft are bent out of whack due to it's low carbon content. So what they do is heat treat the FE to be harder. Now the difference between S25C JIS vs 1025 AISI is that the metal has been verified by an official JIS office to be within Japan's tighter tolerances and requirements. There are only 26 JIS authorizing offices. All but 2-3 are located inside Japan.

Crack! It has a strong possibility it will. Daiwa just created an all new material in their GIII series. Its high COR and doesn't CRACK! They call it neo titan and it's propritary. At PGA show demo day guys that swing 115mph were cranking it over 360 yards with no dents or. cracks.

Mizuno just ended the MP-5, 55, 66. The last 3 models Mizuno made by hand in Japan. No more Yoro custom stamping and grinds 😞

I think VG3 is done. It was always a test of early titleist tech. think T-MB and how it came out years before in Japan. Then the VG3 Type-D is the predecessor to the T100/400 stuff they got going on.

By design I can make an S25C iron feel just as soft as an FE99 iron. Or an FE99 iron feel as hard as I want. S25C is perfect to me. S20C is no difference S15C or SS400 you start to feel the material getting softer but then need to check lofts/lie's more frequently.
