I am looking for gifts for groomsmen, all are avid hunters, all already have field knives. I am thinking about getting them some boning knives for bulk meat processing as well as day to day use in the kitchen. I have a ton on my plate and haven't left myself time to do a ton of research. I have more or less narrowed it down to a Shun Kanso (aus 10A) or Messermeister Oliva (1.4116). I would be open to other options keeping it close to 100 or less. My biggest question is does anyone have a link to direct comparisons of the two steels, just the fact that I cant find a direct comparison makes me think the aus 10a may out class the other to the other point that they aren't comparable? It looks like there are more than a few other names for the 1.4116 I may have already found a comparison but glossed over it. The biggest parameter I am concerned with is edge retention, all of the groomsmen can sharpen a knife but there's nothing more annoying than continually touching an edge up in the middle of a session processing 200 lbs of meat.
