Hello again, Mandy.
Thank you for choosing Mearto. Considering the images, this piece is:

A Damascus steel set of hand-made dragon knives following the style of the Japanese Edo period. Judging from the techniques and the blades they are dated to mid 20th century. Knives made of Damascus steel and various materials that complement the high-quality metal. These knives make fantastic gifts and brilliant showcase pieces. Damascus steel is a high-quality alloy that produces an excellent edge and cutting ability. The knife has a long service life. The blade does not need frequent sharpening and can serve its owner for decades.
