I'm only messin buddy. I would say that 5160 would fall smack between S7(SR77)and 51200( SR101). It would likely chip out quicker than SR77 but not as easily as SR101 and it would hold an edge longer than SR77 but not as well as SR101.

5160 is a great all round steel especially on larger knives. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
