See my post #29 in this thread. The Hattori HD Series are made by Ryusen; Blazen
is another line made by the same company.
I have versions of the HD Series knives with three different kanji -- Hattori's own, Ryusen's, and a third company called Takahisa that is strictly a distributor. The only difference in the knives, aside from size and shape, is the kanji, so if Hattori is finishing the knives, it's either not apparent to me or the other companies are doing an equally good job. It really doesn't matter much, however, as they are all of superior quality.
