Quartus, I think you missed my point. The edge is quite steep, and getting a good CUTTING edge on it is pretty unlikely, even given that it is made from 154cm.
I agree that edge holding is quite important, however, in this case, the edge is not really intended for CUTTING jobs. As I wrote, it is really more of an axe type edge. MOD puts the edge on there to insure that folks recognize it as a knife, IMO. Otherwise, it is simply no more than a how I orginally described it, a glorified ice pick. Any pointy piece of steel will achieve the same effect.
If I were looking for a SD knife for all around use, I would pick something that could not only be sharpened, but hold an edge. It would have to be useful for cutting, not just stabbing. The Ayoob is really and truly only useful for poking holes, with cutting being a very secondary issue.
I have various knives of both stainless, and non-stainless. For the most part, I tend to lean towards properly heat treated L-6 (an almost stainless) as being best for overall work, though I have plenty of others to pick from.
I also am pretty good at putting the edge back, though I try to not get to that point, preferring to touch up as I go along. Easier all the way around.
