Chef Panko takes the same approach with the Shibazi f/208 as he does with the other Chinese cleavers he reviews--including several others by Shibazi: he goes through his protocol. He makes recommendations for pros and home cooks. The Shibazi f/208 has been reviewed and even compared by home cooks like me--and rated by more than 1000 on AMAZON. Chef Panko is just more professional and uses the same protocol on each cleaver.
He doesn't recommend a "best," but he does identify those he considers good ones.
What did you expect?
Only a Japanese native will ever get it right. In the last few months, USC has been asked to participate in a student exchange in which Americans would get their degree at the Japanese University--with all classes taught in English. Although the USC Dean is over there right now, it's almost certain that USC won't participate. The reason: even with classes taught in Englsh, no Americans would be willing to participate.
I'm working right now with three Japanese natives seeking an advanced degree over here. When we meet, my collaborator serves as a go between. Crossing that language bridge either way is at best a work in progress.
