There are sixty three layers of Damascus stainless steel within these knives, which is why they have been made a limited edition line. The edge retention is truly excellent, and when combined with the strength and sharpness that makes these Sakai Takayuki knives so popular. Your comfort and control has been taken into consideration by the designers by creating a large and angular handle, giving you the total control that you require. Finishing off the knife with a wooden handle that has been hand crafted, there is nothing quite like this knife for quality and professionalism.
