Sakon Ryuga is made with the innovated technology of powdered high speed steel,
which is clad between layers of soft steel and has excellent edge retention.
Premium Powder Metal Clad Steel
The core steel SRS15 gives the "SAKON RYUGA" blade an immense strength and incredible hardness of HRC-64.
The fine molecular structure of the powdered steel enables these slender blade knives to glide effortlessly through any task, giving the act of cutting a fluid silkiness.
The remarkable inner core is protected by a layer of softer (SUS405) stainless steel on both sides to ease sharpening when needed which is not often on a "SAKON RYUGA"
Powder Metallurgy for the blade core steel
The added elements of tungsten, molybdenum and vanadium are very effective in contributing to the knife's hardness & durability.
However when using the conventional dissolution method, they tend to turn into rough carbide during the coagulation process.
Powder Metallurgy achieves coagulation maintaining the minute metal structure even when reacting with the abundant matter of these elements.
The powdered high-speed (SRS15) is a material very rich in carbon & these other elements. The "Powder Metallurgy" application produces an idea result.
