Colorful blades

Ryan1226 is a katana whose blade is of the unokubi-zukuri geometry. This blade type is usually common in shorter blades like tanto. The blade of this sword is made of through-hardened, folded 1060 steel with bluish-red, oxidized coating. This coating adds corrosion resistance to the blade. It has two grooves, a bo-hi (wide groove) and a so-hi (narrow groove) which terminates in the middle portion of the blade. The black fuchi, kashira and tsuba are made of iron. The tsuka is hardwood with black rayskin panels and blue, synthetic leather ito in katatemaki wrap. The saya has a partial wrap of green rayskin with polished, buffalo horn koiguchi, kurikata and kojiri. 

The blade is made of 1095 high carbon steel and darkened, the area under hamon presents different color. It's unokubi zukuri, the thickness on the back becomes thinner from the half of the blade towards the tip, but the back turns to thick near the kissaki. There's no yokote. The tsuka is made of hardwood and wrapped with geneuine rayskin and synthetic silk ito. The tsuba is made of iron, fuchi and kashira are made of brass.

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.  

The blade is made of folded steel, after color treatment the folding grains are more obvious. The tsuka is wrapped with genuine rayskin and synthetic silk ito. The tsuba is brass and dragon motif.  The fittings are fully customizable.

Ryan1256 is an entry-level katana. The blade is made of folded 1060 carbon steel which was through-hardened. Being through-hardened means that the blade does not have a natural hamon but the folding process during the forging of the blade means that it has a beautiful grain pattern which is highlighted by its oxidized, blue coating. The coating also adds corrosion protection on the blade. Through-hardened blades are suited for novice practitioners or backyard cutters as they can take botched cuts better.

This blade has a shinogi zukuri geometry with a bohi. The tsuba is made of blackened iron while the habaki and seppa are blackened brass. The fuchi, kashira and menuki are also plain black. The tsuka has rayskin panels painted with blue lacquer. The saya is made of wood with smooth, metallic, blue lacquer.
