Before the popularity of stainless steel, carbon steel was used for most blades. Carbon steel blades are among the sharpest blades available and are much easier to sharpen than stainless steel blades.
What type of steel holds the best edge?
The steel with the highest slicing edge retention has the maximum amount of vanadium carbide and it is heat treated to a high hardness. Therefore among available knife steels we would expect a steel like 15V or Rex 121 to have the best slicing edge retention because of the high MC carbide volume.
What metal is the sharpest?
What is the sharpest metal?
- Tungsten has the highest tensile strength of any natural metal, but it’s brittle and tends to shatter on impact.
- Titanium has a tensile strength of 63,000 PSI.
- Chromium, on the Mohs scale for hardness, is the hardest metal around.
What steel stays sharp longest?
White Paper (Shirogami) Steels
There are three types or grades of Shirogami steel: Shirogami #1 – The hardest white paper steel. It will stay sharp the longest but can be a tad brittle under aggressive use. Shirogami #2 – Most commonly used type of white steel.
What is the sharpest edge?
Diamond blades are the sharpest blades because the molecular structure of diamond allows for an edge configuration that tapers down to as little as one atom thick.
Is S110V better than S30V?
Re: S30v vs s110v
If both steels have upper range hardness and geometry alike, S110V should have higher strength, wear, edge holding but lower impact toughness then S30V. Edge stability is greater in lower carbide steels as long as the hardness is in the upper range.
What pocket knife holds the best edge?
A strong and durable high-quality drop-point pocket knife, the Benchmade Griptilian has a razor-sharp, solid plain-edge 3.45-inch blade which is made from tough American-made stainless steel, and the blade has well-rounded characteristics, a good edge retention and width, and a high corrosion resistance.
Can Obsidian cut through DNA?
Can Obsidian cut through DNA? TIL Obsidian Blades are so sharp that they can cut cells and DNA. They are used are used in modern medicine because the sharp blades create incisions which heal faster.
Can Obsidian cut through steel?
No. Obsidian is relatively soft with a typical hardness of 5 to 5.5 on the mineral hardness scale. In comparison, quartz (crystallized silicon dioxide) has a hardness of 7.0. VERY TRICKY TO CUT STEEL WITH OBSIDIAN.
What is the sharpest sword ever made?
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.
What is the hardest steel for knives?
Carbon steel is a popular choice for rough use knives. Carbon steel used to be much tougher, much more durable, and easier to sharpen than stainless steel. They lack the chromium content of stainless steel, making them susceptible to corrosion.
What type of knife stays sharp longest?
Stainless steel is an ideal material when it comes to knife-making because of its ability to withstand the everyday pressure in the kitchen. It also resists rust and corrosion. The high chromium component in stainless steel requires frequent sharpening for the knife to stay sharp.
What is the sharpest pocket knife you can buy?

Is there anything sharper than obsidian?
Since obsidian will fracture down to a single atom, it is claimed to have a cutting edge five hundred times sharper than the sharpest steel blade, and under a high magnification microscope an obsidian blade still appears smooth, whereas a steel blade has a saw like edge.
Is Diamond sharper than obsidian?
Surprising Things about Obsidian
Surprisingly, the edge of a piece of obsidian is superior to that of a surgeon’s steel scalpel. It is 3 times sharper than diamond and between 500-1000 times sharper than a razor or a surgeon’s steel blade resulting in easier incisions and fewer microscopic ragged tissue cuts.
Can Obsidian cut through cells?
On the cellular level an obsidian knife can cut between cells rather than tear the cells as a steel knife will do. A sharper cut will allow a wound to heal more rapidly with less scarring.
