Konosuke is one of our most popular and sought after brands. Their impressive line of knives encompasses a wide variety of materials and finishes. They construct their knives from some of the best steels available and use blacksmiths that have attained legendary status to craft these fine implements.
The new Sanjo YS line of kitchen knives is a wonderful addition to their canon. Boasting a core of “secret” semi stainless steel, which is very similar to their highly regarded HD2 knives, the blades are hammer forged san-mai constructions with a stainless steel cladding. The core steel is hardened to a high rate of 63-64HRC. The cladding is treated to a beautiful kurouchi tsuchime finish which is artfully applied and feathered into the sublime satin lower blade road. This in turn reveals the inner core steel which is polished to a high luster.
The blade length is slightly over the advertised number, most unusual for a Konosuke, and the height is well proportioned, coming in at 46mm. Grinds and edge geometry are typical Konosuke: first class! The overall balance of the knife is also really well conceived with the use of a gorgeous handle made by Khii Studio from enju and maguro woods.Maker: Konosuke

Whoa! Talk about an intense blade! Stunning blade design and handle work. I love all the character this blade brings to my collection. The YS secret steel leaves an interesting blue patina and is aging well. The Kurouchi finish with the different hammer marks is a real statement! This blade comes out of the handle super thick but has a beautiful distal taper. Because of this thickness there can be some wedging. However, the edge on this bad boy is thin! It will fall right through many Ingredients and is a joy to use! One issue I have come across is that this blade is delicate. I have chipped this blade, there are baby deflections in the blade, and general upkeep makes this a semi tricky blade to care for. And also not necessarily a workhorse. If you're looking for a gorgeous and unique blade for your kitchen I would suggest this blade. But I may not take it into the professional world simply because it is delicate.

Love this knife!, June 10, 2020Posted By: Lew Barrett
I took Mark's advice when buying this knife and I'm really glad I did. It glides through food effortlessly and when you're done with it a quick rinse and wipe is ll it needs. The core "semi-stainless" may be slightly reactive but you can't tell by looking at my knife. A rinse and dry after use and it's ready for the next time. Delivered in perfect condition as promised, I've been delighted with this knife from the first day I got it.

Had this knife for about 3 months now, I work as a line cook and do my fair share of prep. Thing is sharp as ever (ootb was great but put it on my 6k stone to polish up), I haven't sharpened it with anything lower than my 6k stone maybe once a month. Very stiff/hard blade but feels very nimble and light, performs well cutting veggies meats, and even breaking down fish. I absolutely love this knife, the semi-stainless takes a patina nicely and quickly. The patina makes the kurouchi finish and aesthetic of the knife so much more rustic and mean lookin and I like it.

This knife is absolutely beautiful. The textured contrast of the unpolished cladding really make a visual statement and a nice feel holding the knife. The handle on my knife is a few shades darker than what is depicted here, which I prefer (https://bit.ly/2JM2j9u). Balance is great. It is more true to size, a bit longer than my Swedish 210mm Konosuke laser. I know there have been lack of specifics on the steel used, but honestly it is so beautiful I've not let it concern me.
