The main element used inmost of the cutlery is iron, base element of the steel alloy.
Must have element is Carbon, otherwise it's not a steel.
Stainless steel also contains Chromium, 14% or more.
Other alloying elements include V, W, N, Co, Ni, Mo, Mn, etc.
To see the effects of the alloying elements and detailed composition or most of the cutlery steels see the attached links.
High end steels use more of the Vanadium, Molybdenum, Cobalt, Nitrogen, etc.
Although, that doesn't mean simple low alloy steels will underperform for many uses.
Iron (Fe)
it thorium
They're made from stainless steel.
Nitrogen.
Beryillium
Silicon ... or more correctly silicon oxide.
Beryllium
They're made from stainless steel.
Razor blades are made from steel: an alloy of the elements iron, carbon, and often other elements (e.g. chromium, molybdenum, silicon, aluminum, vanadium, titanium, manganese, nickel, tungsten, cobalt) depending on the desired properties.
Razor blades were first used in the Bronze age around 18000 BC. In the 21st century safety razors, whether electric or not, became very popular. In 1901, Gillette invented a razor wit disposable blades.
Single edged razors are normally referred to as safety razors and are used for the removal of hair. All razor blades are made in this fashion for the handlers safety.
Razor Blades are used for mincing specimens, trimming tissue blocks, and which enables the cutting of bulky specimens with far less distortion than would normally be the case.
The first element in the fourth period, which is used in making fertilizer, is potassium.
One use is for making saw blades that cut rocks
Nitrogen is.
The element that is used in the making of supersonic airplane wings is titanium. Titanium is a chemical element with the symbol Ti and the atomic number 22.
Nitrogen.
