Simply designed and magnificently crafted, the Suncraft Senzo Pro Paring Knife is built for performance. These knives feature a core of SG2 powdered steel clad with softer stainless steel. Super-hard SG2 steel stays remarkably sharp without being delicate. This is a robust steel that is built to perform in any environment. Senzo Pro knives offer the best edge retention at 63° HRC with a very tight grain structure for ultimate sharpness. The European style riveted handles are carefully shaped and comfortably finished. 

SG “Powder Stainless Steel” contains more carbon that traditional carbon steel knives (Aogami, Shirogami) but is also high in stainless elements. This means your knife will hold an extremely sharp edge for a very long time. This steel is extremely hard. The harder the steel, the more brittle it can be.
