When I first received this knife, I was impressed. It didn't seem amazing, but it seemed like a solid knife. The finish on the blade was my main concern; it seemed quite rough. I assumed this was the lacquer and immediately decided to remove it with acetone. This made the knife look and feel a whole lot better. I'm starting to like it more at this point
Next was the thinness. It's not as super thin as I thought it would be (although my only other gyuto to compare it to is a Takeda, so I'm not really saying it's a mighty gyuto by an means). That being said, it is quite thin and feels good in hand. The edge ootb, was surprisingly good as it could push cut paper, but I decided to take it to the stones. It went to my Takenoko, Naniwa 10k SS, then Chromium Oxide charged leather strop. The edge was awesome and I was getting really excited to use this knife.
Fit and Finish:
The overall F&F of this knife are quite good. The choil was rounded and the spine was not too sharp. I decided to polish them anyway to give a smoother feel. My one issue is there is a small scratch on the back side of the blade from a slight over-grind. It's not a big deal, but it is noticeable. The octagon handle on this knife is probably one of my favorite features. It is quite robust and very comfortable. I thought I would not like such a large handle at first, but it gives you great control without having to hold it tightly at all. The saya fits beautifully and has a very nice shape.
Wow. This knife is very sharp and the geometry is insane. It is a joy to use this knife. It is incredibly nimble and precise. It's not quite as thin as my Takeda, but the geometry is far superior. I just love the blade shape. The only thing that I have to get used to is the fact that it is an unclad knife; this definitely give it a different 'feel.' Clad knives seem to provide some shock absorption with their softer exterior steels, but my Tadatsuna seems a bit more brittle and hard. This is not a bad thing by any means, I just have to get used to it. I used it qute a bit the first day and the edge held up quite well. Not as well as AS, but that's to be expected. It still push cut newspaper by the end of the evening. And by the way DC, it's getting a very nice patina already
This knife is great and I can't wait to use it some more. The only problem is, it makes me want more knives! I was doing pretty well for a couple months, but the taste of a new knife makes it hard to resist others. Now for some photos!
