Stainless steel is a popular class of material for knife blades because it resists corrosion and is easy to maintain. However, it is not impervious to corrosion or rust. For a steel to be considered stainless it must have a Chromium content of at least 10.5%. [24] 154CM / ATS-34 steels. These two steels are practically identical in composition ...
The steel is then forged into a single plate, and the pieces of cast-iron are piled on top, and the whole thing is forge welded into a single billet, which is called the age-kitae process. The billet is then elongated, cut, folded, and forge welded again. The steel can be folded transversely (from front to back), or longitudinally (from side to ...
The use of wood with rounded edges prevents any cutting injury when sparring but because wooden weapons typically are typically thicker bladed (compared to flat steel training swords like feders) while being of similar weight to steel weapons, they impact much harder than the thin blades of steel training swords (whose weight is concentrated at ...
When cutting a straw target that is standing vertically, the easiest cut is the downward diagonal. This is due to a combination of the angle of impact of the cut against the grain (approximately 30-50 degrees from the surface), the downward diagonal angle of the swing, and the ability to use many of the major muscle groups and rotation of the ...
The Chinese swords had edges made of crucible steel similar to the metal found in Damascus swords, which were welded to a back of soft iron, to give both a hard and strong cutting edge but keeping the rest of the sword soft to prevent breakage. These produced a very hard and visible patterned-edge with a very visible transition at the weld, due ...
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications.
One example of a traditional Japanese patination for mokume-gane is the use of the niiro process, usually involving rokushō, a complex copper verdigris compound produced specifically for use as a patina. The piece to be patinated is prepared, then immersed in a boiling solution until it reaches the desired color, and each element of a compound ...
They can be made from stainless steel, or hagane, which is the same kind of steel used to make Japanese swords. [1] Most knives are referred to as hōchō (Japanese: 包丁/庖丁) or the variation -bōchō in compound words (because of rendaku) but can have other names including -kiri (〜切り, lit. "-cutter").
