To me Handmade will never be the same for everyone.
How about if only 1 person does all steps.Thats handmade to me. Clicker? sewing machine? no matter all the skill for whatever "Tool" was used all came from one person. Let them sign it or something would make it even better even if 50 people are doing it at the same time.
Machine stitched is never hand stitched, but can still be handmade.
I think for leather goods, the hand stitched is what matters most, not the cutting of the leather. people know what hands and sewing machines are even if they do not know their worth. how many even know what a clicker press is?
