What is wireframe-esque design style called? Is it made solely with pen tool?

Wondering what this wireframe like designing style is called. I've seen it for years but never really felt the urge to ask. I also wish to know if it is made solely with the pen tool in ps/ai or if it is a differing method ie.very precise stroke manipulation through multiple layers from an original image be it a 3d render or real life product shot. I honestly don't know how I don't know the specific term used for it seeing as how it is so popular within my community (although mainly mobile and desktop devices).

Thanks for any help you guys can give!
