The 270mm gyuto is the longest knife in the Kohetsu AS Western line and a serious professional tool - built for breaking down large proteins, working through high-volume vegetable prep, and making the long slicing cuts where a shorter blade simply runs out of room. Kohetsu is a CKTG exclusive brand made in Seki City, Japan by a specialist shop we have worked with for years. Aogami Super at HRC 64, stainless cladding, and a thin grind that outperforms most carbon steel knives at twice the price. Note: these knives have a small cosmetic dent below the kanji from the bolster-making process - it does not affect use or performance.
At 270mm this gyuto chef knife features a thinner than average grind that lets the blade pass through food with minimal resistance - a quality that becomes immediately apparent on the first use. The 60/40 asymmetric grind works well for both right- and left-handed cooks. Stainless cladding over the Aogami Super core keeps the flanks protected and simplifies daily care while the carbon edge does the cutting work. The mahogany western handle with stainless bolster and three rivets is well executed - full tang construction, comfortable across grip styles, and finished to a standard that punches above the price point. Fit and finish are of a high standard throughout.
What Customers Are Saying: Note: these knives have a small factory dent below the kanji from the bolster-making process - cosmetic only with no effect on performance.
Care Instructions: Aogami Super is a reactive carbon steel - the stainless cladding protects the flanks but the exposed carbon edge will patina naturally with use. Wipe and dry the blade immediately after every use. Avoid leaving acidic foods on the edge. Hand wash only, never dishwasher. Apply camellia oil for long-term storage. Sharpen on quality water stones - AS at HRC 64 rewards good sharpening technique and responds beautifully to stropping.

Have been after a blue 2 or a an AS 270 for some time and not disappointed! I have a vg hattori petty and a traditional white 2 santoku and the fit and finish on this is really nice. For a large knife it feels balanced and not heavy. Out the box it wasn't sharp. I normally just go a few passes on a 4000 grit stone with my knives and that brought this up easily to a great edge. I chose this (with advice!) as it would be easier to sharpen than the hap40. If it ain't easy to sharpen it'll get dull then what is the point of having good knives? Tested at the weekend on a rib joint and it was majestic! Cutting through gristle bits just be resting the blade on top. Overall delighted, even with the relative high freight and customs for international ;)

I purchased This knife to compliment my wa version 270mm of this blade....Marks designs and specs are once again remarkably shown in this western version....I loved the wa version but wanted something with a little more heft for harder ingredients and bullet proof handle....This knife came with a good edge but i ran it over a few stone and leather strop to get it light saber sharp ( get marks strop set for the light saber effect it was something i was missing on my edges for a while )...and this knife killed everything i put under it....balance is great just slightly behind my pinch but i have a large pinch and at the price the fit and finish is remarkable....anther great co op knife by mark and kohetsu
