Ban, what Superb workmanship & Talent to get a big blade so extremely thin. The Santuko of yours that i have is just under 2mm at the spine which is slender compared to many knives but a relative fatty compared to this hair whittler. My knife slices superbly and has zero flex so it's excellent for a wider range of jobs, such as cutting a squash in half where flex would cause the blade to deviate from a straight line cut.
For an 'all-round' Chef's knife there is an optimal thickness and i think mine is very close to that. This super thin one is more specialized to 'softer than tough old squashes'; i.e. more of a 'Tomato' supreme slicer (and most other veges too) but definitely has a place as 'one of' a selection of kitchen knives.
I do get some edge rolling on mine (i think that's what the edge is showing), but it so far does not seem to impair it's excellent slicing ability. Might this be more of a problem with this ultra thin blade ?
Kitchen knives are really a 'best buy' for us Custom knife lovers because they do get daily use, especially if you are also a gardener with heaps of veges to process like i am. I love my Custom Hunters, Bushcraft, etc. knives, but many of these only get used a few times each year.
Please keep up your interest in turning out a range of what i believe to be The Best kitchen knives being made by anybody, anywhere, worldwide.
