I think the question as asked may be too simple -- I assume that the choice of SR77 is part of the Price/Performance calculation. Are even the basic material costs of SR77 and SR101 equal?

In general, I believe (based on nothing more than second-hand stories and faith that they are truthful) that SR101 is superior for small blades, but that in order to meet expectations in large blades SR101 must be differentially tempered, which I imagine is more costly. Even in small blades, the performance difference is marginal (mainly people saying that SR101 doesn't require sharpening as often), so is this discussion simply dog-matic?
