Obsidian scalpel blade
Actually, the cutting edge of this scalpel is only around 3 nanometers thick. Used by some surgeons by some surgeons, the scalpel blade has a cutting edge several times sharper than that of high-quality steel surgical scalpel blades in the market. Through unknown means, the blade is capable of using its heat to purify chakra it absorbs, making it neutral. What Scalpel Blade is the Sharpest Obsidian is the sharpest scalpel. The blade is sharp and hot enough to slice through steel produced by some forms of the Steel Release kekkei genkai. The obsidian blade is sharper than handcrafted blades and even katana, having a smooth edge even on the microscopic level. Because of its range growth with chakra, it can prove disastrous if the user succeeds in stabbing or even slashing the target. Upon cutting the target, all unused chakra within the closest twenty tenketsu are drained completely, and used to extend the range of the blade, while the heat instilled within the blade cauterizes the cut and any wounds inflicted. The blade can easily cut cleanly through a target with next to no effort due to its sharpness. Upon tilting their hand, some of the obsidian breaks off, forming a long, super-hard, razor-sharp blade.

The user coats their hand in Lava before applying slight shape transformation to it as it quickly solidifies. Kekkei Genkai, Hiden, Ninjutsu, Kenjutsu, Chakra Absorption Technique Even handling an obsidian scalpel takes great care because one can unknowingly cut themselves without pain because the laceration is so fine.This article, Lava Release: Obsidian Scalpel, is property of Princeharris1993. Under a microscope, an obsidian scalpel divides individual cells in half, while steel scalpel incisions look like they were made by a chainsaw. The smaller the angstrom, the finer the blade.Ī household razor blade (King Gillette produced the first safety shaving blade in 1904) is about 300-600 angstroms, while an obsidian blade is about 30 angstroms. Angstroms are a unit of measurement between atomic planes in a crystal. Obsidian can produce cutting edges many times finer than the best steel… and obsidian blades first produced about 2,500 years ago in Mesoamerica can still cut today. Reusability is cost-efficient, but sharpness produces cleaner and more precise cuts with quicker healing and less scarring. However, obsidian… a type of volcanic glass… has re-emerged. Stainless steel later took over, due to its reusability and resistance to corrosion. Years ago, most scalpels were made of nickel or chromium-plated carbon steel. An obsidian blade is 3 nanometers thick, capable of cutting BETWEEN your cells, allowing for a much more painless surgery. Other features like shape, balance, uniformity and dependability are critical. After the 1st and 2nd World Wars, the American industry caught up in manufacturing leadership.Īs elective surgery rose to prominence, the individual needs out of a scalpel have morphed and now must meet certain requirements. For a time period, barber-surgeons were prominent in the US, embellishing their scalpels as part of the art of their craft. America historically has always imported knives. Surgical instrument-making, as a profession, was noted in the 18 th century in England, France, Holland and Germany. Roman surgeons relied on armorers who made cutlery for wartime as well. Copper in 3500 BC, bronze and iron in 1400 BC. How the scalpel was made has varied over time.īlades were initially composed of sharpened stones like flint, jade or obsidian, but metal blades replaced them. Interestingly, the shape of the scalpel likely has not changed much over time.

Wounds happen on the battlefield while incisions happen in the operating room, so “scalpel” implies security associated with healing. Furthermore, a “knife” can be used by anybody, but a “scalpel” is only used by a surgeon. If anyone else takes a knife to another person, it’s a criminal attack. “Knife” connotes danger and is more likened to a weapon associated with mutilation and death. Modern surgeons have embraced the term “scalpel” over “knife”.

“Scalpel” comes from the Latin word, “scallpellus”. Hippocrates may have been the first to describe the surgical knife, termed the “macairion”, a smaller version of a Lacedaemonian sword called a “machaira”. Flint knives were used as scrapers to cut through the skull in trepanation. It’s evolved, changing form, to meet our needs.Įvidence of knives used in medicine may be traced to the Mesolithic period around 8000 BC. The knife is hypothesized to have existed for more than 2 million years, longer than modern humans have walked the Earth. Amongst the list of the most useful tools in human history, the knife is usually at the top.
