Once you've made your point, there is little benefit to keep repeating it. It's clear you prefer Japanese knives. Good for you. I'm sure they can be great. Others prefer European style knives. I'm sure they can be great. I like the knives I have been using for over 20 years. I sharpen them myself and they do all I ask of them. They may be the Japanese or European. Not important. Let's move on.I didn't refuse his opinion. I refused his fact. The fact is that Japanese knives outperform forged Euro knives because of their thin hard blades. I can prove my position and have proven it to the Wusthof rep that calls on my company. It is fine to prefer forged Euro knives to Japanese knives. It is not fine to argue that they perform as well as the thin hard blades of Japanese knives. It is incorrect. Sorry. Probably time for me to leave. Take care.
