Flawed/imperfect is a good thing !
Check out Bohlin's buckles. The cuts are very crude BUT ! these crude cut buckles bring $30,000-$40,000 !
I have a friend who produces buckles along the same style. His cuts again are very crude, but again he gets on some work $50,000 and $60,000 .
Folks with money don't want something that looks like it came from a machine.
As I have said in the past , I incorporate file/hammer marks in various places on my spurs to give them that handmade/used look.
There is even a culture in the Far East? who produce beautiful works of art and then go back and intentionally put flaws into the work.
Their rationale is that nothing man creates is 100% perfect.
The engraver with the flawed work that you reference is one that I highly respect due to his truly hand made work.
IT HAS CHARACTER !
