The core of these exceptional knives at the same time holds the secret of their quality: a thin layer of high-alloy "Double X VG 12" carbon steel. Based on a special formula that goes back to the founder of the company, this contains ingredients like cobalt, manganese and molybdenum. The result is that all the knives of the 1778 series have an elastic and cutting core unit, coupled with an extreme degree of hardness (amounting to 61° HRc). This is a combination that not only gives you incomparably fine and even cutting, it also lengthens the service life of the cutting edge considerably. As carbon steel is liable to corrosion and is not neutral in terms of taste, the core of the knife is sandwiched in between layers of high-alloy steel.  The handle of the 1778 series is made of Plum Wood. Each knife is made by hand, each handle is as unique as from where the wood came from the tree. The knives come in a special presentation style gift box and each knife comes with a Plum wood sheath as well.
