MM's... not centimeters. A Takeda is not a few mms taller, it is dramatically taller. The 60mm quote that you see floating around is an approximate, and a modest quote at that. They are hand made and vary, but the 240's are laughably tall.
It's hard for me to comment on this because I despise
240 Takeda Gyutos. I take offense to their height. They are humongous Santokus - cleavers with a pointed tip tacked on the end, and they are absolutely useless to me. JUST ME! They are top sellers, and I guess that must be for a reason; though I can't fathom for the life of me what that is. I don't like how they cut, and ironically I'm seeing some complaints about grinds just pop up. These are only 2 very isolated incidents out of thousands of knives, but I don't like the knife... I just don't like how it cuts
.. period. Other styles, even other sizes, different story, but 240 "Gyuto"... NEVER.
I'm not quite as large as LUCA,
but I do have catchers mitt hands
that are pretty scarred up as that is apparently pertinent somehow, and I won't use any knife over 53-54mm tall. On a 270, maybe I'll push up to 55, but grudgingly. I feel you lose way too much dexterity swinging around all that useless steel. I want as least in my hand as possible to do the job, perfectly.
If you want the darker handle on the left, it can be installed for $60. BUBINGA INSTALL<--link
If you want the custom handle/ferrule on the right with custom blade thinning, it can be had, as well. TAZ575<--link
