Aye. It's a business. If you do it fulltime and do nothing else and get wide distribution like Ralf Aust, you can make a living. And keep in mind Ralf Aust also starts with premade blanks. Anyone having to start with plain stock is never going to run a business with a sub 100$ razor no matter how basic the design. Suppose that you make 100$ profit on a razor. Starting with plain stock, it takes several hours to make a simple razor.

But that 100$ is only 100$ when the customer pays it.
Between that moment and the moment the money is 'yours', the taxman has dropped by.
And he knows words like VAT. Social security. Income tax. (yes those are 3 different things that need to be paid) and then there is also county tax. Zoning tax. Business surface square meter tax (no kidding). I think I also pay environment tax.

That 100$ quickly turns into 20 actual dollars that you can spend. For several hours work.
Oh wait. But you also need liability insurance and medical insurance.
I guess ramen noodles are on the menu

Dovo is the epitome of mass market razors that are western made and still decent quality. And they make in large volumes and use stamped blanks. Logically, any attempt to compete with dovo for much smaller quantities and at a lower pricepoint is doomed to failure when economic reality sets in.
