Here is another of my vintage Japanese knife blades. This one was made by the Japanese craftsman, Genshin (see picture 6) in the tradition of the samurai sword with hand forged high carbon steel that holds an edge like no other in the world. The back side is slightly concave giving it a hollow ground cutting edge. View the enlarged pictures and you can actually see the lamination in the blade edge. It shows very little signs of use. ( in excellent condition ). It is still razor sharp and has a generation of life for its next master. Measures a compact yet functional 10 inches overall (25 cm) when sheathed in its hardwood case. Overall blade lenght is 5" (12 cm) with a cutting edge 2 3/4" (7 cm).. Old world craftsmanship for the new world craftsman.You'll love it, I guarantee it .........If you purchase this item and are not completely delighted with it, you may return it for a no questions asked refund within 14 days of receipt.
