well, it always depends on what one considers as "high performance"...
i started with a Wuesthof Dreizack Classic 4582 chef's knife and thought it was great for years...
then my cousin gave me a Yaxell Ran Santoku. although i never really liked the knife as a whole i like its blade.
then it was a Hattori FH/KF gyuto. it's a reliable and great performer with the best handle i've ever had.
then it was a Konosuke HD gyuto. this is serious sh*t! sharpness out of the box is terrifying! :scared4:
and then i had the chance to grab myself a Hattori KD gyuto. i love it in every regard, and this is what i consider not only sharp but this is pure beauty.
