Tojiro Flash features a blade that has a folded and forged construction of 63 layers of Damascus steel. This process allows the thin center layer of VG-10 steel to be extremely hard & sharp but the blade retains flexibility & strength. The unique design of the graduated bolster allows for easy re-sharpening all the way up to the heel of the blade along with a totally smooth, comfortable, perfectly balanced feel. With a Rockwell rating of 61, these true damascus blades provide a superbly sharp edge that you would expect from a top quality Japanese knife. The Micarta handle is inlayed with stainless steel for a stunning appearance. Micarta is a revolutionary new handle material that is made from linen and synthetic resin compounded by extreme amounts of pressure and heat creating a wood-like grain and feel for ultimate durability. Made in Japan; Lifetime warranty.
