Boning knives are a special type of kitchen knife that typically have several design features that help with boning meat, fish, and poultry. Boning knives have a narrow blade and the typical size of a boning knife is 12 cm to 17 cm in length on the blade.åÊ

The primary use of this knife is to remove bones from cuts of meat. This knife is often used as a dagger with the blade facing away. The curve of the edge is designed to cut up to and around bones. This is designed for trimming around bones, NOT cutting through them.

For many years, chef knife manufacturers have been trying to achieve the ultimate cutting edge which is rated using a Rockwell degree scale - the highest being Rockwell 62å¡. 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 has overcome this problem by using a layer of super hard steel, Rockwell 62å¡ sandwiched between two layers of softer stainless steel, Rockwell 10å¡, to produce the ultimate chef knife cutting edge. We call this Triplex Steel Technology. The layers are infused under high pressure and temperature so the molecules intermingle to a depth of 18 - 24 microns - so separation is impossible. However, the softer layers act as protective shock absorbers to the knives cutting layer.

All the chef 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 15å¡ angle, which allows for wonderful slicing and portion control.

The unique handle design distinguishes I.O.Shen Mastergrade 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 we do not recommend dishwasher cleaning).

The handles of the chef knives are bonded to the blade steel using stainless steel rivets. Unlike aluminium rivets, these are corrosion resistant and have the same effect of expansion as the blade steel. The handles will remain secure for life.
