This Katana is hand forged and hand sharpened using Japanese methods to create the perfect blade. The blade is made of T10 High Carbon Steel that has been hammered down and clay tempered with a polished mirror-like surface. This evens out the carbon content and creates a beautiful wave pattern on the blade. It is strong enough to cut through a thick bamboo tree with a single strike yet sharp enough to slice paper. It is durable enough for cutting tameshigiri and bamboo. Each sword is individually handmade so specifications vary slightly from sword to sword.
