After what seemed like forever, I finally got my new Nubatama yesterday! Mine is 240mm and the maker calls it a "Ryu-Ba", which I guess mainly means double beveled knife. This one is a bit of a mystery. I don't know the artist who made it nor will anyone reveal the slightest peep as to just what "Black Steel" is. But stainless it ain't, it will patina a bit.
The first really striking thing upon unboxing is the finish! The knife was sharpened and polished by a sword polisher in Japan and the finish is unlike anything I've ever seen before. I'll try a few pics but I don't think they'll really do justice to this beauty:
The profile is very flat. I'd say it's kind of like a cross between a Masamoto KS and an Akifusa. Even compared to other Wa-knives I have it's incredibly light. I'm having some issues with my digital calipers (grrr!) so I can't say how thick it is but think thin
The next thing you immediately notice is be beautiful convexing on this baby. I'm not sure any of my pics really show it. Let me try one I took at work with my phone:
Well, hopefully you get the idea... :P
At any rate, the edge on my Nubatama is incredible. If you've never used a knife sharpened on Japanese natural stones it's hard for me to describe that's simultaneously toothy and smooth. Right out of the box as a good I tried to push cut a free dangling paper towel...well, it push cut from 2" out! It falls through everything like it's not there. So a polished edge, right? Not so fast! You razor guys would say it's not "shave ready"- when shaving hair you can feel it pull. But not like a 3k synthetic stone pull...no, it's very different. Here's a close up of the very edge:
