It does look like a 3d mock up to me, possibly autocad for the design spec. Which they'd prob use for the manufacture stage anyway. Then feed that design template into rhino 3D with flamingo pluggin and finished in photoshop to blend down and make more realistic. Not uncommon to have early prototype looking this realistic for even a newbie to design work if its basic know materials, wood table, different metals etc. The software has so many presets that if you have a good cad spec file its easy.
But as for the razor looks nice but just not into a thors hammer in weight for my shaving tool lol. It would prob be a statement piece in a glass cabinet unless made of titanium or aluminum to cut down weight. And the hex alankey bolts on top appear to be how the head cap and base plate are located/held together. That would be a mission every time to change the blade.
