Smooth shading is driving me nuts

[Tobias_Tobias]

Hi there,

I have made a simple shape: a cube, beveled some edges, made quads out of all faces and still I get this stripy shading when smooth shading and/or using a matcap. It appears where the edges are close together.

How can I fix that?
Thanks so much for your help!

It is normal. You can not create perfectly smooth edgest with manual. Youmust create low poly model, after that apply Subsurf modifier for perfectly smooth surfaces.
