You know, there is a very best at everything. I have seen guys that are the very best at bronc riding, at high jump all the way down to spinning pizzas and playing the french horn. Yours happen to be making the duck whistle. Nobody, and in my opinion nobody, does these like you do. I have made a few, but I have a bad habit of holding what I do up against someone elses. I have looked at all the makers here and in person and know I shouldnt. Those are way beyond pretty. Bout as good as they can get. Italy? Wow! Thy reputation precedes you. I actually sold one to a guy in Italy once. But our Italy is 12 miles from here, Italy, Tx.lol. One question, sir. what size tool do you use for the holes. I assume you have said before, but I cant find it.
