Ancient quenching:

Modern vacuum heat treatment can meet the hardness requirements of most swords, but the traditional quenching method has better effect, can soften the medium strip steel, and the hardness is higher.

 

Brass cast by dewaxing:(No extrusion casting)

We use the traditional lost-wax method for casting mountings, which is a precision casting method for metal implements. Practice is made of beeswax casting model, and then fill the core with other refractory materials . After heating, the wax mold is melted and lost, so that the whole casting model becomes an empty shell. Then the molten brass water is poured inwards, and the vessel is cast. The utensils cast by losing wax can be exquisitely carved and have hollow - out effect. The effect of the production of the installation is more delicate, three-dimensional sense is stronger, the consumption of man-hours is more.

Kobuse:

The vast majority of modern katana and wakizashi are the maru type which is the most basic, with the entire sword being composed of a single steel. The kobuse type is made using two steels, which are called hagane (edge steel) and shingane (core steel). Steel of different materials is forged and welded together to hammer the basic shape of the sword. This allows the overall blade to have a higher toughness and absorb a lot of impact. Reducing the possibility of breaking or bending to some extent. Makes the blade not only has high hardness, but also has super toughness.

 

T10 carbon steel:

The best quality of high carbon steel is T10, the carbon content was 1.03%, and the element contains a small amount of chromium, molybdenum, vanadium, after heat treatment can reach HRC 58-60 hardness. Toughness is very good, but it is not resistant to rust. It is applied to traditional european-style hunting knife, large cutting knife and military dao.
