These knives are fantastic. I've had lesser quality knives including ceramic ones and the quality has never compared to the Professional "S" series. I had a 8" chef's knife of a different series that I gifted to my brother after he used it on a visit. He wouldn't stop talking about how smooth it felt in his hand and cut with ease. I wasn't too upset, knowing I had been looking at this series.

If these last as long as my previous, I'll have them for many, many years. Simple care is all they need. I never got to a point where I needed to send them off for sharpening.
