Trezor Keep Metal punching issui

Hello

I have order the Trezor Keep Metal.

After I pre mark the 4 letters and try to punch it with the punching tool the is no way I can do that.
It’s like steel and nothing happens. No matter how hard I press. And I don’t hear a click. How much strength needed to press it down?

How is the punching tool screwed together? I had it apart once and now I’m not sure if I screwed it back together correctly.

Is a production error possible and therefore it cannot be pressed down?

How to doing that? At Step 3 it don’t work. (I don’t can put the link of you Guide here)

The is no way I can it press down with the punching tool. I hit the punching tool with a hammer. Nothing happened.
