If you just started your own sword collection and plan on getting a Japanese Katana sword,this article is definitely for you (another Katana enthusiast!). A sword truly worthy of respect (and worship by some),the Japanese Samurai sword is a fascinating combination of engineering and art to learn much about.This article is written with that task in mind focusing on the basic sword terminology.
The Japanese Katana developed in the 16th
century is undoubtedly the best martial arts weapon ever created. It was
broadcasted so in several international documentaries and certainly deserves
this title with its technological perfect structure and fearsome cutting
capability allegedly able to split a man from throat to groin in one swing.

Learn about the basics of Iron Casting, types of
IronCasting, and the process of Iron Casting.
Iron castings can be referred to as products made out of
melted iron molecules. These molecules are, first, poured into mold and allowed
to cool. They are then extracted. The casting properties depend a great deal on
the foundry practice. They also depend on the cooling rate. Iron contains huge
carbon concentrations. This content facilitates melting, simplicity of casting,
and machining. Iron casting designs have a great variation owing to the
property of iron to resist shrinkage during the process of cooling. The end
product attains a great reputation for its strength and durability. Tensile
strength ranges between 20,000 psi and over 60,000 psi. The values of hardness
(without heat treatment) range between 100 and 300 BHN.
