Marc, I have a Yusuke special thin 240 Gyuto that is largely my go-to knife for prep unless I want more detail in my cuts then go for my Mori Nakiri. I have on order the 210 Swedish, 61RC, flatter profile with a 2.8mm spine above heel. As much as I love the special thin, I'd like something with a thicker spine. I spoke to MPukas last week (his knife in that review), he still raves about it. Reach out to BlueWayJapan (Keiichi), he's absolutely great to deal with and will gladly accept back any knife if your not 100% satisfied.
Yusuke come in three configurations:
Standard non-customized White #2 Special Thin
Standard non-customized White #2, Spine thickness around 2.2
Customized and special order, Swedish Stainless, extra hardened to 61RC and in a flatter profile
He can get them in 210, 240 and 270. Come in Magnolia/buffolo ferrule. can get them in other woods but take longer
Keiichi said my knife would be available in April.
Will post my review after. Also you can see my other review hereon the Special thin 210 I got
The knife is was way under valued, but when demand increased so will the price. you know how that goes
