Create Greatness -Art of Sharpness

Like a house building that needs architectural concept, accurate measurement, scientific methods and labor and resources, building a knife is a delicate yet complicated miniature engineering that makes wonders from a hunk of flattened metal, that is, create exceptionally sharpness from a blunt steel.

Strength from Within

    Many steels look alike on the exterior though, internally they have major differences. Different steels are made of different formulas -- a little more carbon or chromium here or there and the performance can vary. Usually, a steel used for making knife is called tooling steel which generally contains carbon (C), chromium (Cr), vanadium (V) and molybdene (Mo).

  • SHAN ZU GYO series -- mix of three steels Cutting edge -- Japanese steel (0.95%-1.10% of C, 13.00%-14.50% of Cr, 0.10%-0.27% of V, 0.10%-0.31% of Mo) Outer Layers -- 430 & 431 stainless steel

  • SHAN ZU Pro series -- mix of three steels Cutting edge -- Japanese steel (0.95%-1.10% of C, 13.00-14.50% of Cr, 0.10%-0.27% of V, 0.10%-0.31% of Mo) Outer Layers -- 430 & 431 stainless steel

  • SHAN ZU Elite series -- mix of three steels Cutting edge -- 9Cr18MoV steel (0.95% of C, 17.00%-19.00% of Cr, ≤0.60% of V, 1.00% of Mo) Outer Layers -- 304# & 440A stainless steel

  • SHAN ZU Classic series -- single steel X50CrMoV15 stainless steel (0.55% of C, 15.00% of Cr, 0.20% of V, 0.80% of Mo)

Thermal treatment - Heat Works Wonders

  • Are all blades from the same steel alike? The answers are always NO. Significantly, thermal treatment makes a difference through which a blade is finished from a “raw” steel. Thus the inherent characteristics of the steel can be changed. The finished blade usually has an elevated hardness, corrossion resistance, flexibility and better cutting performance. Heat treatment is complicated and it requires skill to bring out the very best that the steel can offer. The quality level of the finished blade from one manufacturer may perform very differently to that from another.

  • Attain The Full Potential of The Steel The steel is heated to over a thousand degrees Celsius to change the propertities of the steel The blade is then quenched momentarily to achieve optimum hardness and elasticity The blade is finally cooled to the room temperature to gain good corrossion resistance

  • By carefully controlling the heating and cooling speeds of the blade, SHAN ZU knives are able to produce an extraordinarily strong blade.

“Kiritsuke” Tip -- Looks Just Cool

  • Every knife has a pointed tip on the blade, used for piercing or delicate cutting. SHAN ZU GYO knives craft a dramatic bevel on the tip, like a sheer cliffside, producing a breathtakingly adventurous beauty. Compared with the smooth tip as many knives have, “Kiritsuke” tip is more aggressive and fiece, which fillets fish and meat more easily.

Professional Polishing

  • Refine the shape of a blade and improve its aesthetic value.

  • A good polish can greatly improve the beauty of a blade, while a bad one can ruin the best of blades. More importantly, inexperienced polishers can permanently ruin a blade by badly disrupting its geometry or wearing down too much steel, both of which effectively destroy the sword's monetary, historic, artistic, and functional value.
