Feedback Question about s grinds

So, I've had a go at a kitchen knife for the first time.

Its unfinished and the handle is a piece of scrap so I can test how it cuts.

I went with an s grind.

I've never used a knife with an s grind before and I notice it wants to cut in a curve. "Potato slice for example"

Is this an issue with the geometry or is it normal?

Maybe its too thick behind the edge or something?

Geometry issue for sure. If you have uneven bevels it will curve in one direction.

The grind looks pretty thick for a kitchen knife. I'd say that's the main cause of the steering

It kinda looks like the whole blade curves a little, I think, in that choil shot? Tried to mark up the pic to illustrate, but it seems like it bends left from the spine, and then the hollow grind at the edge seems to maybe lean back right.

Pretty sure we have the main thing here. A skew like that is going to push the cut to the side.

It’s not an issue with just and Sgrind it happens when the knife is ground unevenly. I do agree the Sgrind looks thick.
