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.
