What knife steel gets the sharpest?
Carbon steel blades are among the sharpest blades available and are much easier to sharpen than stainless steel blades. The lack of chromium in the blades means that it is highly susceptible to rust and corrosion and requires careful cleaning after each use.
What metal can be the sharpest?
The sharpest object ever made is a tungsten needle that tapers down to the thickness of a single atom. It was manufactured by placing a narrow tungsten wire in an atmosphere of nitrogen and exposing it to a strong electric field in a device called a field ion microscope.
What is the sharpest type of knife?
Obsidian knife blades: overkill for slicing your sandwich. The thinnest blades are three nanometres wide at the edge – 10 times sharper than a razor blade. These are made by flaking a long, thin sliver from a core of obsidian (volcanic glass).
What is the sharpest blade in the world?
Obsidian knives
Obsidian is not particularly hard (unlike diamond), it’s just capable of being very sharp. Obsidian knives have however been used in medical procedures where very precise cutting is required and where laser surgery is not available.
What is the sharpest weapon in the world?
Damascus swords — sharp enough to slice a falling piece of silk in half, strong enough to split stones without dulling — owe their legendary qualities to carbon nanotubes, says chemist and Nobel laureate Robert Curl.
Is glass sharper than steel?
Modern glass knives were once the blade of choice for the ultra-thin sectioning required in transmission electron microscopy because they can be manufactured by hand and are sharper than softer metal blades because the crystalline structure of metals makes it impossible to obtain a continuous sharp edge.
Do expensive knives stay sharper longer?
While expensive knives might stay sharp longer and feel more nicely balanced in your hand, the real key to having a sharp knife is to sharpen it when needed. A paring knife is the second blade to have. These are for getting into hard-to-reach places and making quick work of any scraping or fine cutting.

What kind of steel has the sharpest edge?
High carbon steels take a very fine edge, but geometry probably is as important as the steel. My sharpest is a Scandi in 1070 by Ivan Campos.
