Thanks for the link; I generally look at these articles with a bit of technical skepticism (and while wearing my "Materials Engineer" pointy-hat), and the normal disappointment didn't take long;
Don't know as much about knives in particular but the above is technically incorrect.Hardness in knife steels is often referred to as strength
Metallurgically speaking, not even close to correct - hard to even begin to go over all the reasons why this is wrong.[Toughness] also defines the steel's ability to flex without breaking
Oh my goodness; :duh2:Also, the measurement of toughness is less standardized as hardness.
(emphasis added)Abrasive wear comes from softer surfaces coming in contact with rougher ones.
[...] hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
-----Fracture toughness [...]
The linear-elastic fracture toughness of a material is determined from the stress intensity factor () at which a thin crack in the material begins to grow. It is denoted KIc and has the units ofor.
Plastic-elastic fracture toughness is denoted by JIc, with the unit of J/cm2 or lbf-in/in2, and is a measurement of the energy required to grow a thin crack.
[...]
Fracture toughness is a quantitative way of expressing a material's resistance to brittle fracture when a crack is present.
Might be an interesting CPF poll, "More paid for a flashlight or a knife ??"; wonder how the breakdown would turn out ...[...] But who am I to judge, I once paid $300 for a flashlight!
