Kitchen Knife
If it is possible to hypothetically thin it to the limit with a blue paper supermarket, it will probably be a kitchen knife that can cut in the world. However, it will be broken immediately as "Pokin", and it is certain that it will not be used. Besides, I can not make such a mon. If you want to make a knife that does not need blue paper, you only need to increase the content of carbon. You can make as many cutting blades as you can. It is better to make it with carbon only, but it is a story to use it for what.
In short, it is an application, it is a problem of a tie.
To cut iron, stone, or big things, use high-temperature high pressure, various beams, gas and water jet. Perhaps such a tool would be the best tool in the world.
But such things are not knives and we have nothing to do with it.
According to a rumor (smell of gash) somewhat across the ears, the assassination unit of a certain country applies the technology of CNT (Carbon nanotube) as a micro "weapon for cutting the neck" so that it is not noticed by the enemy even when it is disarmed I'm carrying an invisible wire (for cutting).
Of course, such a mon is useless and the guillotine is no good, and Cesium rays are out of the question, and blades like sea boomerangs like Eye Slugger at the head of Seven are obviously not.Such things are good irrelevant (lol) Cutlery is not just sharpness but balance.you can also visit for more kitchen and hunting knife to go this handmade Damascus hunting knives.
[ Hardness ] [ toughness ] [ abrasion resistance ], contradictory characteristics have to be well-balanced well and it is now time to demand [ corrosion resistance/corrosion resistance ] in addition to this.It is broken, there are vegetables, long cuts, easy to sharpen, not rust is easy to say, this is this thing, all like magnetic pole repulsive nature, that balance set is an eternal theme.If the hardness is increased, it will break, but toughness and tears will disappear and it becomes fragile.Carbon steel increases its sharpness depending on quenching (hardness increases) but it is brittle and rusty.Although stainless steel is sticky, it is hard to process and hard to have high hardness.Cutlery steel is a history of how hardness and toughness are distributed.Sharpness and Structure of
Kitchen Knife Hardness and Sharpness
In terms of high hardness, that is, sharpness, "Japanese sword" is outstanding, and there were scenes where TV gun bullets were cut off before on TV. However, because its corrosion resistance and toughness are weak, it is easy to break and easy to break. Japanese swords are extremely fragile to the impact from the side. However, the forging technology is probably the best in the world. For limited use, it will be the best in the world.
Japanese sword is made of ancient tatara steel making by [ball steel], but carbon steel [Blue paper No. 1] succeeds this flow, it can be cut well, but there are problems with corrosion resistance and toughness. It would be good to say that the blue paper was developed to make it durable.
