I. O. SHEN 20cm FLEXIBLE FILLETING KNIFE

The Triplex Technology used in the I O SHEN range of knives is explained like this; The harder the steel, the longer it retains a razor sharp edge, but hard steel can be brittle. This problem is solved by wrapping two reinforcing layers of softer, shock absorbing Rockwell 10 steel around the core of ultra sharp Rockwell 62 steel.

This combination of high tech materials and traditional hand finishing skills has produced an exceptional range of knives.
