I would have to say that the Tamariz Knives are very good. I will not venture to say the best, because I haven't seen them all.
The only thing I do not like about the set is that the blade is not a quality blade. I think is made in China.
As far as the symetry goes the knife it is great. Also very flat, with no flashes whatsoever, very nice to work with.
I'm pretty sure I can manage to get them from Spain.
If anyone is interested, post it here in the board, since I am on my way to Spain.
As far as the routines ,do not pass the moves published in Sonata, by Juan Tamariz, and GET BY ALL MEANS, Ascanio world of knifes, which still remains the masterpiece in the subject.
