To render in wireframe you need to set the material to wireframe in the materials tab. I don't know how to render a wire + solid. I guess maybe set the "edge" settings in the render tab to a very high number will do it.
Ehhm need help for the blade How I make the fuller? tried sculpting but it's hard since I need to subdivide the sword and it gets very "fat" and Idk how to make it look like it was before but with the fuller So that's the question. (I already have the sword safe without the subdivide)
248 quads.
Will get to texturing in one or two days.
I think you could save a lot of polys here. Remove the helper edges on the hilt and blade, they don't add to the silhouette so you don't need them. Remove some of the extra topology from the pommel and grip, and make the points in the middle of the blade floating topology to save some more tris.

Remodeled it to try and eliminate some more polys and to show you that it would look very much the same
198 tris, and the silhouette looks identical to me.
I think you could reduce a lot of polys by sharpening the edges and reducing the polys of the holes, or using alpha maps to fake it. And I think the decorations on the guard could be made in to floating topology to make it cleaner.
