Miura & Miuraism iron head size

[Ara selai]

In case you're curious how Miura blades compare in terms of head size, I put together the attached images for reference, compared to a golf ball.

It's a pretty smooth transition from one to the other in terms of size.

• The Miuraism SB01 and 1957 LE blades are identical in size.
• The MB-5003 and Tournament Blades are identical in size; proportionately wider and taller than the SB01/1957 LE; slightly wider and shorter than the SB02.
• The SB02 is the tallest, but is a little less wide than the TB/5003.

Note that the maximum difference (SB02-->SB01) in height is 7 mm (a little more than a quarter-inch), and the maximum difference in total length (5003-->SB01) is 3.5 mm (about one-eigth of an inch). So the differences are pretty fine. Having hit them side by side, I'd say, though, that the SB01/1957 is noticeably smaller than the others. It has to do with the way the ball looks snuggled up against so small a head.

Also note that the location of the center strike point shifts outward with increasing clubhead size. I have no idea how this relates to the actual sweet spot of each club, but the total L-R difference of the three strike points is less than 3 millimeters. How closely can you groove your swing???

Final bit: I think it's interesting how the grooves cover far less of the club toe on the SB01/1957 and 5003/TB than they do on the SB02. Again, no idea what it means, but it's one of the subtle things that really differentiates these clubs besides simple dimensions.

Anyway, I'd be interested in any comments....

My gawd thats the best post ive ever read

where on earth did u get all those miuras?

Can i send u all my irons and do the same analysis for me so i know why i like what i like

bugger it ur sherper is geting12 7 irons next week for analysis!

Stunning review

Thanks, Stew. I reckon it could be improved if I could display the actual sweet spot (COG) as well as the cetered strike point for each club.

Great stuff m8. I love the size of the 1957/sb01. It was very daunting at first. When I shank, I shank em all the same wether Gi irons of baby blades lol. I like the fact that the ball looks huge when I'm addressing it rather than thinking omg that head I so small.

My 3i is the CB202, such a different swing feel with the extra metal hanging far from the shaft. Your last diagram probably explains that.

In relation to swing plane, I didn't make any changes.

Cheers

Ara, I'm speechless! That's a candidate for post of the year! Seriously

Great stuff and initiative for putting that up. Now if we could all compile

Date and possibly add other brands if irons to the database that would be awesome.

If there was a bowing down icon I would use three of them right now.

Props bro!

Thank you for your passion, Ara!

Hi Ara,

Nice post.

A couple of corrections though as I see you are using the measurements and graphics from Miura Giken.

B is not the sweet spot length. It is the face length as the sweet spot does not span the entire scoreline area.

The strike point won't necessarily equal where the COG is though you are correct that typically COG is shorter in a smaller more pro oriented head vs a larger more forgiving head.

Very nice work. Keep up your great contributions.

I was wondering why a 25 hcp would torture themselves with all those blades!

Nice work!

@stevo. I hit irons pretty well and prefer hitting blades at the minute. They're fun to shape shots with, and the feel is unbeatable. Short game is my Waterloo. I think I'll be around 10 once I clean up my wedges and putting. It's usually one or the other that lets me down, on average once a hole with a lazy swing. An extra chip from the fringe or an extra putt. The rest is pretty solid, although i plonk a wayward drive or turf a shot frequently enough that I doubt I'll ever see scratch. I'm picking up a set of SB01s next week.

@gocchin. I'll make the corrections you suggested when I'm back at my computer with the original files (next week). No idea where to find COG data. Any suggestions? I also hope to add a few clubs next week. Can someone post dimensional data for Epon AF-Tours or Yamaha Tours? Or anything else they'd like to see? Happy to add files as the data get accumulated. If measurements wait for me, it'll be whenever I hit something new.

Thanks for the encouraging words, guys. Glad to contribute.

Great post! I dont follow your thinking about more upright swing in relation to blade size/shape/dimensions tho.

@ant. Thanks for the reality check. I re-read what I'd written about swing plane and centered strike point, and it made no sense to me either. I deleted the sentence from the original post.
