Steak Kitchen Knife - Blade 4.33" - N690 Stainless Steel - Hrc 60 - Black Technical Polymer Handle

The Due Buoi Steak Kitchen Knife in the special "Olimpo Knives" section has a 4.33 in long not serrated blade in N690 stainless steel with "EXTRA DURO" heat treatment.

We have reached a value of 60 HRC although this is not our only goal because hardness without important flexibility is harmful.
It is not easy to have knives that with such high hardness values remain sharp for a long time and at the same time easy to sharpen.
The critical factor is the flexibility that prevents the edge from microfracting. ruining the sharpness itself.
The flexibility also allows the blade to "feel" the steel for easy sharpening.
This combination of factors requires a special treatment developed over 140 years and which the Due Buoi calls it "EXTRA DURO".

While to ensure the necessary sensitivity and safety during use. the ergonomic handle in black technopolymer is full tang fixed with three stainless steel rivets.
