Please rank the available (North American) stainless types by their ability to achieve high initial sharpness and resist initial loss of edge retention.

The application is high end kitchen blade (one paring, one Santoku) that is not used for abrasive materials and is touched up before dropping below high cutting efficiency. Even mix press and slice style cutting. Accidental hard surface contact (plate pot etc) will occur but has/will be minimized through training and nagging.

I am confused by some materials with a coarse(r) grain structure, but high attainable hardness (S90V) vs finer structure but lower attainable hardness (AEB-L).

Kitchen knives have long been divided by the softer/loses edge quicker/sharpens easier vs harder/holds edge longer/harder to sharpen.Your choice ! From hard to soft maybe - S30V, CPM154, 154CM[ATS-34], VG-10,440C, AEB-L. A typical Henckels or other European blade is on the soft side .I retired my Henckels for Shun knives [ VG-10 ] and I'm happier ,it's a harder ,better combination for me. I have knives of most of the other steels I mentioned but not kitchen knives. The softer steels are sharpened with a steel but the harder ones might be better sharpened with a diamond or ceramic.Don't worry about grain size [they're all fine enough for the job ],and hardness isn't all important either.
 
Dont really have an answer for the question, but would like to take this oppertunity to thank METE.

You always seem to have the answers to our questions no matter how technical. THANK YOU your input has made mine and i am sure a lot of others, lives a bit easier.:)
 
Thanks for the reply - sharpenability is not a high priority - my focus is on initial edge quality and initial edge retention with the usage pattern spec'd.

i have been using cpm154 and love it
i didnt see the need to have all the V in s30v in the kitchen
the last santoku i made helped me cut 5 yards of fabric into little bits no bigger then my pinky nail and was still able to shave arm hair:thumbup:
