The blade is honsanmai structure, 1095 high carbon steel is the core steel and cutting edge, folded steel is the jacket layer. The grains of folded steel is clearly visible.

The handle and saya are made of hardwood, polished buffalo horns are used as fuchi and koiguchi.

Odachi or nodachi was a type of traditionally made Japanese sword used by the samurai class of feudal Japan. Odachi are difficult to produce because their length makes traditional heat treatment more complicated: The longer a blade is, the more difficult (and expensive) it is to heat the whole blade to a homogeneous temperature, both for annealing and to reach the hardening temperature. The quenching process then needs a bigger quenching medium because uneven quenching might lead to warping the blade.  

This odachi is intricately forged in the honsanmai lamination structure. The edge is made of 1095 high carbon steel which has high hardness while the sides are made of folded steel which has high flexibility and has a beautiful grain pattern or hada.

This odachi is differentially hardened and has a visible hamon. The tsuka is wrapped with genuine rayskin and synthetic silk ito. The pattern on the saya is shell patchwork. The koiguchi, kojiri and kurigata are buffalo horn. The fittings are made of copper.

Ryan1335 is a beautiful blade with a deep koshi sori curve and shinogi zukuri geometry. The blade is made of differentially-hardened 1095 steel with no bo-hi and designed for heavy targets. The sori is 2.8cm at the deepest point and the very appealing kissaki measures 5.5 cm.

The tsuba, fuchi, kashira are all made of iron. The seppa and habaki are made of brass but chromed to give it a silvery appearance. The tsuka is made of hardwood fully-wrapped with black, real rayskin and reinforced with cotton ito. The saya is made of brown hardwood partially-covered with white rayskin and then painted over with clear lacquer to show the very attractive wood grains. The koiguchi, kurikata and kojiri are made of polished buffalo horn.

This katana is intricately forged in the shihozume lamination structure. The edge is made of 1095 high carbon steel which has high hardness while the sides are made of folded steel which has high flexibility and has a beautiful grain pattern or hada. Iron is used to form the softer core of the blade. The shihozume lamination is a labor-intensive forging technique that requires high skill level on the part of the swordsmith. Imperfect fusion or welding of the different steel types on the blade can cause the blade to delaminate or split.
