Working in an industry where rapid prototyping is the norm, I've been thinking about one shot manufacturing methods for blades.
Using subtractive modelling techniques from cad, it seems feasible (in my head at least) to make a razor from an hardened/tempered blank. This could be achieved using cnc electro discharge machining. These things can come of the process with hair splitting tolerances and mirror finish if required. All that would be required is to hone and scale.
I know this would take the fun out of things but have others thought about this. Cost may be prohibitive but if I can get a favour done I will attempt to get this done sometime but may have to get a physical model digitised. Am I missing something here? 3D printing is a rapid growing technology and the day will come sooner that low cost custom one offs will be the norm.
Any thoughts?
