GENERAL USES OF THIS KNIFE
The Gyuto is the Japanese version of the classic Western chef's knife but the blade tends to be thinner and holds a sharper edge. A gyuto is similar to a utility knife in that it is a multipurpose knife that can handle virtually every task including chopping, mincing and slicing meat, fish, vegetables and fruit. Our gyuto has a western style handle and the blade is a Japanese inspired profile with a k-tip nose and a fair amount of belly in the blade to allow for a gentle rocking motion.
CPM- M4 CARBON STEEL
The blade on this knife is composed of a high carbon CPM M4 steel. M4 is the best carbon steel we have ever used in regards to blade performance. After doing a wide amount of research on this steel, we decided to give it a go and have been extremely impressed with its performance thus far. CPM M4 steel is unique in that it gets extremely hard. We took this blade to a solid 66 HRC. The hardness allows it to maintain amazing edge retention but unlike other steels at this hardness its not as brittle or delicate. It is actually highly wear resistant which means you don't need to worry as much about the knife chipping or breaking. As an added bonus, M4 is surprisingly corrosion resistant when compared to other carbon steels.
Its a rugged knife for the performance it offers and this combination is rare when you harden steel to beyond 62 HRC. (Please note though that the steel isn't bullet-proof...if you drop the knife on a very hard surface or slam it down on a hard object, it is likely to chip.)
The pros of this steel outweigh the cons but it must be mentioned that this steel is harder to sharpen than many others so you will need to factor that into your decision as it does represent a bit more maintenance than other knives. On the flip side, you don't need to sharpen this knife nearly as frequently as others. *Note that we provide free sharpening on all of our knives and we are always happy to help in this respect.
**As this is a carbon steel, the blade will form a slight patina over time. This is normal and is actually the mark of a beautifully used knife. Please note, however, that a carbon knife does require more maintenance than its stainless steel counterpart, mainly that it must be washed or wiped clean shortly after each use to prevent unwanted rust or stains. We have acid etched this knife and created a stonewashed, pebbled finish to protect the steel and start the patina process. Over time this etch will fade slightly and will be replaced by the individual patina you make while using the knife.
HANDLE DESIGN & MATERIALS:
Every one of our knives is handmade, unique and numbered. NORA#1164 is a mix of stabilized walnut and teal dyed box elder burl wood. Both have been stabilized for durability. Separating these materials is a stripe of twill carbon fiber. Pins are stainless steel and liner is a gray G10. The combination of all these materials makes for a modern but classy look.
Wood stabilization is an added feature that we offer with our knives. Wood that is stabilized has been injected with a clear acrylic resin under a vacuum process. Stabilization helps to minimize, if not eliminate, any cracking, warping, shrinkage and/or expanding of the material. Stabilized wood will not absorb water and is generally impervious to oils. The process helps to ensure your knife has a long lifespan in the kitchen.
