Tamahagane knives from Niigata in Japan use VG-5 stainless steel to manufacture a fantastic range of traditional Japanese knives. VG-5 is used for the central core and is similar to VG-10 stainless steel but considered slightly easier to sharpen and better for edge retention. Tamahagane San Tsubame knives incorporate a 3 layer construction with the extremely hard VG5 steel core sandwiched between two softer layers of stainless steel for protection and flexibility which feature a hand hammered finish . The 3- layer blades are complemented with a classical fine Micarta handle that provides the great looks and feel of wood while being more durable. Micarta is a pressed linen material that is infused with resin, creating a comfortable grip with no maintenance required. These razor sharp edges are skillfully honed to an ultra sharp 14 degrees and are highly polished. You must be over 18 to buy this product.
