IO Shen Knives

For many years, knife manufacturers have been trying to use increasingly harder steel in order to achieve the ultimate cutting edge. The hardness of stainless steel is measured on a scale called Rockwell; 62° being the highest grade commercially available. However, the brittleness of such hard steel has always been a limiting factor.

I.O.Shen has overcome this problem by using a layer of super hard steel, (Rockwell 62°) sandwiched between two layers of softer stainless steel, Rockwell 10°, to produce the ultimate cutting edge. It's called the Triplex Steel Technology.

All the knives in the I.O.Shen Mastergrade range have used the very latest technology to construct a blade that is not only amazingly sharp but will also retain their edge for a phenomenal amount of time. They have been hand sharpened to a 15° angle, which allows for wonderful slicing and portion control.

The unique handle design distinguishes I.O.Shen Mastergrade Knives from any other knife. It is an essential factor in achieving balance and stability. The Tai Tang is not simply an embellishment, it is an integral part of the handle.

The handles are produced from a synthetic material, called ebonite, which is both durable and heat resistant (although dishwasher cleaning is not recommended).
