Picked up what I think is this knife but from another source:
My purchase looks almost identical, save the kanji, which doesn't quite line up.
Now, after a some digging I am a little confused as to what I actually have.
First off, the Kikuichi site calls it a Usaba but it is a nakiri, unless those terms are used somewhat interchangeably (kinda like by definition a square can be a rectangle but not vise-versa).
Bumping around their site, translations and product descriptions leave a lot to be desired.
Although it seems Kikuichi may brand some other makers as well, I believe this particular knife is their own.
The description for my knife was this:
"KIKUICHI ELITE GOLD WARIKOMI NAKIRI SLICING KNIFE"
However I don't have a lot of confidence in the listing either.
The knife is new and unused, but perhaps old stock and this: "INCORRECT BOX".
Not sure on the core steel but the description called it a high carbon core. No patina yet (non acidic vegies so far) but it might be either VG-10 or V-Gold (whatever that is, but the "Gold" would fit the listing description), or some japanese mystery steel. Doesn't "feel" like VG-10 I have used before.
The cladding appears to be on the softer side.
It has deep clean kanji and the Kikuichi chrysanthemum stamp.
Regardless, a very nice knife.
Good fit/finish, thin, and got real sharp real quick.
My first nakiri and fun to use.
Anyone have one in this series or know something about Kikuichi ?
