Remember that SR101 is a modified 52100 steel. This steel is a favorite wth custom knifemakers for it's overall cutting abilities and fine grain. It definitely has better edge holding than SR77. In it's differentially treated state it is not far behind INFI or SR77 and for hammering it's spine it may be better as it is softer in the spine than the oters giving it more impact absorbtion. Really at this point you are talking which knife you like the looks of most, more so than what is better. They are all so good that you will never know the difference.
