One knife came to mind, and I make it as a kitchen knife. If made correctly, the knife is strong and effective, but difficult to manufacture. In my case, it is easy to make it as a 3D model. If it looks practical, it has some problems in use, but if you consider only kitchen needs, then there are no problems.
Resolution - 1024, 2048, 4096. Cards - BaseColor, IOR, Metalik, Normal, Roughness.
The files turned out to be a bit bulky, due to the textures and their detail content. The knife has the right dimensions.
At this point, knives making gets a pause.
