I.O.SHEN 170mm Boning / Filleting Knife (KW_K005DN)

The secret of I.O. Shen Mastergrade knives is the centre layer of Rockwell stainless steel that provides the ultimate cutting edge, and which will retain sharpness for an extraordinarily long time.

For many years, knife manufacturers have been trying to achieve the ultimate cutting edge which is rated using a Rockwell degree scale (liken it to degrees Fahrenheit) - the highest being Rockwell 62° (this is like the boiling point of water). However, the brittleness of the knife has made this impossible to produce commercially without using a Damascus method, which is very expensive. I.O. Shen have overcome this problem by sandwiching 2 softer outer layers of steel with Rockwell 62° to produce the ultimate cutting edge. We call this Triplex Steel Technology. All the knives in the I.O. Shen 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 also been hand sharpened to a 15° angle, which allows for wonderful slicing and portion control.

The distinctive handle is specially designed for balance and stability, which makes these knives a favourite with many professional chefs. The blend of high technology materials and traditional hand finishing skills has produced an exceptional range of knives. The I.O. Shen Tai Tang handle is not just an embellishment but it is actually an integral part of the handle frame (the tang). Since the I.O. Shen Mastergrade knives were launched in the UK in September 2004, they've had an impressive impact on this competitive market and are favourites with many professional chefs including Jamie Oliver and Anthony Demetre. The unique handle design distinguishes I.O. Shen from any other knife brand, as well as improving balance and handle stability.
