Devin Thomas 210mm Wa-Gyuto. The Devin Thomas ITK is one of our favorites. AEB-L gives you the best of both worlds, the convenience of stainless with the ability to take an acute edge. AEB-L steel was designed for razors, which need corrosion resistance, high hardness and very acute edges. Once you try a knife that is made with AEB-L you will see why it is coveted by knife enthusiasts and professionals. The knife will take a very keen edge just like the best carbon steels yet you don't have to worry about rusting. You will also find much better sharpening properties since AEB-L is less prone to produce wire edges that are so common when you sharpen most high end Japanese kitchen knives.
