In my experience the Benchmade S30v is about as stain resistant as the 154cm and it holds an edge significantly better. That is just one advantage to the Ritter mini over other mini Grips.
The other advantage, (and the bigger advantage) IMO is in the actual design of the blade.
The high, flat grind and deep, wide drop point is an unbeatable design. I out shines other knives particularly when working with wood. It is what has me constantly going back to my RSKs (I have both the large and the small) for EDC both on and off the pavement and leaving my other knives (including some real quality knives like my CRK sebenza that is also S30v) in the drawer.
So, I guess my answer is that IMHO the Ritter (large or small) is well worth the extra $$ you pay as compared to the other Grips from BM.
