im not an expert ,this is my first Purchase of a Katana but i did ample amount of research before Choosing Shinken of sword as the Maker of this Fine piece , the product i got was delivered in a week , it is put together with decent skill, it cuts objects of medium hardiness like butter , it is well balanced, feels good when held, produces a nice air slicing note when swung and the Hitatsura Hamon is just Mesmerising to look at, i Praise the Craftsmen who took their time to bring this piece to a fine Finish.
