Hello all, A few months ago I came here looking for advice and I got quite a bit of quality information. Thank you for that. So when I chose a knife I knew I would be happy with it. The knife I chose was an Amazon purchase for the Yoshihiro Aoko blue steel knife. I will go over some initial thoughts and a little deeper as I have been using this knife for quite a few hours a day for a couple of months now. I will not be posting links, sorry, this site just doesn't care for them sometimes. I can take specific measurements at another time as it is currently unavailable. Initial impressions are that the knife is an eye-catcher. The hammered and sand-blasted finish look wonderful. Made in Japan. Happy packaging and a booklet of lots of knives I can't afford came along with the knife. The knife is very light. The carbon-stainless sandwich looks fantastic. This is coming from someone that has quite a bit of German workhorse experience. Also that the knife feels much smaller than it's 210mm would seem. Which isn't big by any means, it just feels immediately nimble. Edge is decent, I feel that I can get a equal or better edge myself, if I have the time. Medium-time impressions is that blue #2 steel is wonderful. After repeated use and sharpening this knife makes my older softer stainless knives seem like a chore to sharpen and maintain. though I really thought it would hold an edge longer, I spend a fair bit of time sharpening the knife. This is also part edge addiction I suppose, as once you handle a very sharp knife that's all you will ever want. But I am starting to notice a fair amount of hand fatigue and the knife doesn't quite fit my large hands and long fingers. The blade itself if very shallow and the handle is small. I do a fair amount of all cutting I would say. I use it to break down all types of vegetables/root veg/melons/fishes/animals/fruits. Push/pull cuts, rock chop(i know), slicing, dicing and I even make julienne fries. I do not shy away from anything with this knife and it hasn't let me down. Also being so light, the weight of the knife does no work for me. The blade has only once earned some micro-chips which was a mystery, but also very easily fixed. The carbon sammy has a petina that looks great BUT I have already made it to the softer stainless in some areas. Which is noticeable while sharpening -- you can feel when the softer steel hits the stone. Final thoughts. So just recently my knife took a vacation. An unplanned vacation. During a multi-chef event another took it home by accident. It is my understanding that it is on it's way home as I type. But it has forced me to use other knives and there is somethings that I noticed. I still don't care to sharpen soft stainless but I do miss a deeper blade. Not necessarily a round belly, but just more room for my fingers. I broke out my old cleaver and my hand really got to stretch out, and that felt pretty good. I realize this Yoshihiro Gyuto isn't the workhorse I am using it as, and it has held up wonderfully. It is an awesome knife and a solid purchase, especially for the money. I just saw it on Amazon for $144. It will always be in my knife bag from here on out, but I think it's time for a bigger knife, something in the 240- 270 range. My cleaver will probably get back into rotation but dang if that thick blade(by Japanese standards) doesn't take some work to edge up... I will be looking for a knife when I am prepping the whole kitchen, then I can switch back to this little beauty when it's GO time and space is short and edge is key. Unfortunately the stainless sandwich is cool to look at but ultimately a let-down for it will be gone soon, this micro-thin layer of blue #2 wears out fast. This is the perfect home-cook or short term usage knife, but for as much as I use this knife I feel I am asking to much. Am I glad I made this purchase? Absolutely. If it doesn't get returned to me would I buy it again? Nope. To many other fish in the sea.
