Classical Musashi Sky and Sea Handmade Katana

Blade: The blade of the sword has been hand made with High Carbon Steel. The Carbon has been hammered out through the blade so that it has a universal hardness throughout the entire blade. A Bo-Hi has been added to the top of the blade to even out the weight and gives audible feedback. The sword comes full tang with a Chu-Kissake.

Saya: The scabbard of the sword is wooden with a high gloss black finish. The black cotton sage-o is tied around a copper Kurigata. The Koi-guchi is black bull horn.

Tsuba: The Tsuba is blackened copper with a design of Sea and Sky. The Habaki of the sword is a one piece brass construction. Two brass Seppas secure the blade in the Tsuka.

Tsuka: The Tsuka is wooden with an real ray skin Same. A black cotton Ito has been wrapped over the Real ray skin Same. Blackened copper Menuki are on each side of the Tsuka rendered as dragons. Two bamboo Mekugi secure the tang into the Tsuka. The Kashira is a relief of waves in blackened steel.

Carbon Steel
Carbon steel, also called plain carbon steel, is a metal alloy, a combination of two elements, iron and carbon, where other elements are present in quantities too small to affect the properties. The only other alloying elements allowed in plain-carbon steel are manganese (1.65% max), silicon (0.60% max), and copper (0.60% max). Steel with a low carbon content has the same properties as iron, soft but easily formed. As carbon content rises the metal becomes harder and stronger but less ductile and more difficult to weld. Higher carbon content lowers steel's melting point and its temperature resistance in general.

* Mild (low carbon) steel: approximately 0.05–0.29% carbon content[1] (e.g. AISI 1018 steel). Mild steel has a relatively low tensile strength, but it is cheap and malleable; surface hardness can be increased through carburizing.[2]

* Medium carbon steel: approximately 0.30–0.59% carbon content[1](e.g. AISI 1040 steel). Balances ductility and strength and has good wear resistance; used for large parts, forging and automotive components.[3]

* High carbon steel: approximately 0.6–0.99% carbon content [1]. Very strong, used for springs and high-strength wires.[4]

* Ultra-high carbon steel: approximately 1.0–2.0% carbon content [1]. Steels that can be tempered to great hardness. Used for special purposes like (non-industrial-purpose) knives, axles or punches. Most steels with more than 1.2% carbon content are made using powder metallurgy and usually fall in the category of high alloy carbon steels.
