Thank you all for the kind comments. I personally delivered it to the customer today. I made the knife based on rough sketches we made in my office. We had discussed steel, handle material, sheath design, etc., but not a price. He just said "make it, let me know when you are finished, and how much I owe you".
A "pleased customer" doesn't quite describe his reactions. I thought he was gonna hug my neck

. When I quoted him the price, he looked funny, and said, "I was expecting to pay twice that amount". Oh well............ live and learn. My wife says I'm giving my knives away....... maybe I need to let her start pricing them.
He was so happy that he ordered a bowie style based on a knife on my website, and between him and one of his friends, he left me six knives to make sheaths for.
The main thing is that he was a "happy customer". That, to me, is what really counts.
