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 with less belly 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 long, western style handle with a thin nimble neck which makes the knife easy to grip and form into your hand. The blade is a Japanese inspired profile but with just a little 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. 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 slam it down on a hard object, it is likely to chip.
The pros of this steel outweigh the cons in our opinion 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.
**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 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 #1238 is a mix of materials including stabilized black palm wood as well as a red-hued urethane based resin. The resin also has small veins of silver in it which is complimented by the three stripes of G10 that separate the two materials. The liners are red and gray which continues the color scheme we were working with on this one.
We decided to engrave a heart on the front side of this blade as a visible reminder of all the painful joys we associate with this vital organ. Our heart seems to be the tangible representation of that part in us that wishes, feels... hopes. How strong is the human heart...it breaks again and again, and yet, lives on!
I added a quote that I love on the backside. It rang true with Steve and I when we started this company.
"It's impossible," said pride.
"It's risky," said experience.
"It's pointless," said reason.
"Give it a try," whispered the heart.
*This knife has been custom engraved. The engraving was done via laser so there is depth to the engraving more so than you see with an electro etch. We do, however, keep the depth minimal so it does not catch much 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.
**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 absorb very little water and is generally impervious to oils. The process helps to ensure your knife has a long lifespan in the kitchen.
