the pics of the first knives on the right on your page are the Tamariz knives, they are the same type he uses, but he is not the manufacturer.
Some time ago they were made by Luis Trueba, and ilustrator of some spanish books, by Tamariz, Ascanio, and Carroll. Then someone else took over the manufacturing of this knives. He is a friend of mine.
The can bu purchased through Steven Magic Emporium, and in every magic shop in Spain. There are a bunch of color combinations made in these type of knives. If anyone is familiar with Antonio Romero Hold out, he does a routine with this knives in his demo video.
The paint on these knives are on the inside part, so they will not chip away. They are almost flat, no flashing of the other side will occur even at eye level when placed on the palm of the hand, but not to a point where you cannot do the paddle move with them. (As a matter of fact is pretty easy to do).
If anyone wants more info on these contact me.
