The NASU Series offers rugged utility with thoughtful design. Each piece is hand-sharpened and features a unique 67-layer Damascus blade, fully forged from proprietary X-7 high-alloy steel. The ultra-dense slate G-10 fiberglass handles are crafted with a slow, deliberate process resulting in a unique finish of added texture and drama.
HIGH ALLOY 67 LAYER DAMASCUS X-7 STEEL
Our proprietary X-7 Steel is harder steel than German steel which means it can take a significantly sharper edge. A unique, Damascus pattern is formed in the metal from folding 67 layers of steel together. X-7 Steel has a hardness rating of 60±2 on the Rockwell Hardness Scale.
ULTRA6 HEAT TREATMENT
It took 3+ years of research and development to dial in the specific heat treatment process that would ensure our knives are both hard enough to take a sharp 16 degree edge, yet durable enough to keep that sharp edge during heavy kitchen use. Every blade goes through our precise ULTRA6 heat treatment which brings out the best qualities of each steel allowing the blade to take a remarkably sharp edge.
SUPERIOR PERFORMANCE
How SHARP is it?
Initial Cutting Performance[ICP] is a measurement that reflects how sharp the knife’s edge is after it has been sharpened. Any score over 110 is considered excellent while a measurement under 30 is rated as very poor.
How long will it stay SHARP?
Total Card Cut[TCC] is a measurement that reflects how long a knife will stay sharp and resist wear through use. Scores over 550 are considered excellent while scores under 100 are rated as very poor.
