Mike, yes. KnotSlip, got it! I AM on the right track. Except I think the terms got turned around again. Isn't bending ability "strength" and impact resistance "toughness"? Where did I put that Advil! <img src="/ubbthreads/images/graemlins/crazy.gif" alt="" /> bending is toughness.

hmmm...
sorry, but I'm throwing two steels into the mix...
so my sr77 edge deforms easier than my 5160 does...
Also, my sr77 will bend further laterally (and easier) than my 5160, but the 5160 will snap with a load that sr77 will only take a set on.
what would I conclude about which of these is tougher, and which is stronger.
once again 5160: harder to make flex laterally. will snap with a lighter load than sr77. resists edge deformation.
sr77: will flex easier laterally. will not break easily laterally, but will taker a set easier. edge deforms easy.

so in the end, how does SR77 stack up against SR101? <img src="/ubbthreads/images/graemlins/frown.gif" alt="" />

Uhhh no Bruce - the other way around...SR-77 is tougher (softer/more deformable) and SR-101 is stronger (harder/less deformable). <img src="/ubbthreads/images/graemlins/ooo.gif" alt="" /> ok, thats what i was thinking too.

lets try some deconstructive logic... toughness is to SR177 what strength is to SR101? <img src="/ubbthreads/images/graemlins/frown.gif" alt="" /> or is it....Sr77 is to toughness what SR101 is to strength? Any Derrida-esque thinkers here? <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

wait, so strength is how weight it will take (gradually applied increasingly) until the knife snaps?
or deforms?

Well there you go.
Let's go back to SR77 and SR101.
If I've got this right, SR77 is STRONGER than SR101 and SR101 is TOUGHER than SR77. So SR77 will accept more gradually applied weight before it breaks than SR101 will but SR101 can bounce bigger, faster-moving bullets off it than SR77 can.
Do we agree with this statement? ohhhhhhhhhh now i see the picture in your head. annealed, i don't think there will be a difference in toughness or strength between the steels. hardened to 59hrc, i can see your picture working. after that, i think we go back to either steel failing under the same conditions. are we only considering 'sweet spot' scenarios? Simple steel is Iron and carbon. More carbon means harder steel. Spring steel has very little carbon. 1095 steel is .95% carbon and the rest is iron. Every steel has a makeup of different elements - steel in it's simplest form is just Iron and Carbon...The more carbon the harder the steel. Heat treatment can change everything for a steel- it can make it butter soft or it can make it brittle like glass...But the laws we are discussing still apply - as HT makes it tougher it compensates strength and vice versa.. Here is basically what I am trying to get across... Lets say I have a piece of SR-77 - By HT'ing it I can make it stronger (more heat) or tougher (less heat) - but as I increase one - the other is going to be compromised. But you have to think of this with one steel- not comparing 2 steels like 77 to 101.
