I have the Mirage #7911 with ti framelock and Acuto 440/AUS 118. It's only about 2 inches or less blade. The larger "Grey Ghost" Mirage was IIRC AUS6.
About the only thing I noticed is that it's not a "pretty" steel. Kind of dingy gray like or more so than 440V. ( compared to the very bright AUS10A).
It came with an excellent edge, and still has it. I don't really use it much. The Ti framelock is well made.
To be honest I don't think they made any M16's in Acuto 440. I think they really made only 1 or 2 knive styles in it for 1 or 2 years. Try to find some now, it's difficult to do.
Sorry I don't have performance data on it but I wanted it for my collection of different steels, and it's too small for practical use for me. Joe
BTW, Junglee knives makes several knives in AUS10A, made in Seki . They are well made liner locks. Knifecenter of the internet is discontinuing several models. I like the steel if only for it's looks. Spyderco is phasing out it's one and only Aus 10A knife. I'd have to let Sal explain as to why. I like it myself, though I wouldn't expect it to perform like VG10, or S30V.
