Okay, I am uncomfortable leaving this unaddressed while brethren read it and believe it.
Aikiyoda, you will get a large number of people supporting this view, it is a commonly believed myth, so lets look at it.
People hear a lot about how "hard" the knife steel is as a selling point. Rockwell hardness indicates toughness, and is not a good indicator of the important qualities of steel used in a knife
Crucial qualities are strength, toughness, creating an edge and holding that edge. These last two are the major factors.
All of the Japanese brands I named are superior to the German makers, including Wustoff, henckels/Zwillings and every other German knife maker.
If you compare to Shun and Global, Shun wins slightly on that, but Global wins on balance and beats Shun by a mile in usage, both lose to the Fujiwara and Masamoto.
All of them beat the European steels used in knives.
Shun loses because of the loss of function due to aesthetic design factors, the top line to point makes it far more difficult (comparitively)when slicing vegetables or even a bigger drawback when dicing whole onions down.
If going for Shun(which I just wouldn't), I would avoid the Classic line altogether.
They baffled me by using VG-10 steel in their 3 layer damascus blade but they used this exemplary steel in a cosmetic way only, yet it is the far superior knife steel out of the 3 used!!
Cannot fathom that, except it is proof they place form way over function.:doh:
You can order Japanese knives from Japan with a 7 day delivery and total safety, once you know what you want.
Buy a good combination stone, like others have suggested too!
