Puukka

I´ve recently tested both and as far I can say the difference is that minimal, that the differences of a Burbank 3*to another Burbank 3*, because of tolerances, might be bigger than the difference between a Burbank to Kanstul.
I´ve also recently tested my Burbank 5* (at the moment for sale, if interested) with another 5* and they sounded slightly different.
