GENERAL USES OF THIS KNIFE:
Our take on the classic Chef knife. This is an extremely versatile knife that is a jack-of-all-trades worker and one of the single most important knives in a kitchen. Our Chef knife design can easily accommodate both a pinch grip and a full hold. It is a good choice for those with larger hands or those who prefer a full hold on the handle. Our design is also excellent for those who like a rocking motion while cutting.
HANDLE DESIGN & MATERIALS:
Every one of our knives is handmade, unique and numbered. The handle on this NORA is a fairly simple design combining durable ironwood with a white G10. The two are cut at a steep angle and then combined. The engraving mimics this same angle and we love the overall look. Liners on this one are a deep, royal blue. It brings just a small pop of color and if you know our knives, you know we like color.
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 can be treated to a very high hardness. Hardness in steel generally equates to a finer edge and great edge retention. We took this blade to a solid 66 HRC which is incredibly hard compared to most production knives which fall in the mid to high 50's.
The high 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 try to muscle it through a very hard object (i.e. hard gourd, thick bones, etc.), 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. 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.
**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. (Some staining or discoloration will be inevitable as a result of the food the knife comes in contact with.) We have acid etched a portion of this knife 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.
**This knife has been custom engraved. The engraving was done via a dual diode laser so there is depth to the engraving more so than you usually see with an electro etch or CO2 laser. We do, however, keep the depth minimal so it does not catch food and minimally interferes with the primary cutting function of the knife. A small amount of stickage is normal around the engraved area, especially initially. This will lessen over time as the blade is used. Please note though, if performance is your #1 priority then we encourage you to NOT purchase this blade. A blade with no engraving WILL have a smoother glide than a blade with engraving. For most, however, this difference is so minimal that it is barely noticed. We just like to provide a full disclosure up front so you know exactly what you are purchasing.
The engraving should last as long as the knife but please note that it will slightly degrade over time as abrasives are used on the knife. We recommend the soft end of a sponge with soap and water for cleaning and mineral oil periodically to condition the blade (and handle). Keep in mind that stronger abrasives, such as steel wool, scotch brite pads, sand paper or stone sharpening directly on the engraved image will further degrade the image.
