Make your own razor ?

Hello everyone,

I first started with a mühle R89, and as i work in a machining shop, i would like to manufacture a razor out of brass.

First things first, is it a good idea ?
Second, wich razors would you recommend i try before settling on a design ?
As i have a rather sensitive skin and shave quite regularly, i would like to keep the closed comb design, but i'm open to every recommendations.

Thank you all for reading this far, have a nice shave
