I agree with Jon. I don't have a lot of experience with single bevels but it is obvious for me that there is no differene between yanagiba, deba and usuba. Those are single bevels which where thought to thin and sharpen on the stones. I bought new deba few days ago and the first thing I did I put it on the stones, flattened blade road and sharpened. Also I wonder why so many people here are buying expensive knifes and they can't do simple things like thinning. No offence here but I think that if you have nice gear then you should be able to take care of it and the only way of doing it is trying.You will do mistake, damage something and next time you will know what to do and what you shouldn't do. Here is my movie which i recorded for the contest. This is the first time when I am thinning and sharpening deba.

So the convex bevel can just be done on a flat bench stone?
Yup... I do it all the time
I buy expensive knives, but then don't do simple things like use it everyday for its intended purpose. I think in a way it's better to learn to use the knife and then use a lot than to learn to maintain it.....
Convex on a flat stone is doable with practice. Easier to maintain a knife that has been properly set up than it is to break in a new one though.

How much thinning Are you actually doing with a stone like that? When I think of thinning a blade road or damage repairing, I'm thinking 120 stone.

Yes, its all about how much pressure you apply and where, how and when you apply it, then blending.
Just remove the same amount behind the edge that you are removing at the edge, do this at every sharpening and the knife should not really get thick behind the edge over time.

Chef Niloc you can see ''part 4'' in the title. I started with beston 500. It's in my videos.
my 0.01 cents input.....
True they are all single bevels, each designed with different profile , geometry and thickness for it's intended purpose(s).
My turning point is sharpening single bevels is when I realised that I have to be more aware of the pressure applied especially towards the final or finishing stages and generally, as long as I respect the profile and geometry of the knife, there is very little likelihood that I will destroy a knife. Essentially, it is steel removal where you want to make two angles meet and have it thin enough as per your preference. Whether it is flat or convex (hamaguri; also how "pregnant" it is) it is still your choice as it has its advantages and disadvantages.)
Also once metal is removed you cannot put it back and thus better to be on the cautious side as to grit and pressure applied.
AS long as it cuts beautifully adn the feel is goood... and does not chip easily ( too thin) I am free to do whatever makes sense to me, within the logical parameters. It's just a knife to be used and derive pleasure and joy when it is put to task.
Finally, I intentionally keep a slightly dished stone for the convex sharpening. Strokes Towards the end of the stones will leave obtuse angle and strokes that terminates in the center will end with more acute angles... OR so it seems. In any event longer strokes by nature generally tend to leave convex edge anyway as most people lack the granular control to compensate the fact that as the strokes move away form you, the angle tends to be higher..
Have a go and fun with it. I didnt destroy the Mike Davis Deba. I had fun with it.
HAve fun adn Stay sharp....
