In the spirit of metal information, found this on blade forums:
S7 Impact toughness at Rc of 57 = 125 (ft-lbs) CPM3V Toughness at Rc of 58 = 85 (ft-lbs) CPM3v Imp.Toughness Rc of 60 = 50 (ft-lbs) A2 Impact Toughness at Rc 60 = 40 (ft-lbs) D2 Impact Toughness at Rc 60 = 21 (ft-lbs)
S7 really stands out!
If SR-77 is anything like AngelSword's S7 with ThermaCycle (and Dan's comments make me think it is), its toughness in the same impact test is 250 ft-lbs.
Whether SR77 is closer to 125 foot pounds or 250 foot pounds of toughness, it's a world away from the fantasy-land bs about stainless steels being tough.
