Am I correct that in additional to the Shigefusa knives I am accustomed to seeing (e.g., as sold by JNS), Shigefusa also sells some of its knives through one or more other distributors (e.g., Kiya), which may rebrand them, or at least sell them with a kanji different than the ones at JNS, etc.) -- but all such knives are nevertheless made by Tokifusa Iizuka (and/or his two sons, Masayuki and Yoshihide)?
