I remember handling a new Mili, with the sci-fi lettering on the blade. The liner felt thin to me, compared to let's say a Wegner, don't talk about a Gunting.
Maybe "nesting" it makes it much stronger than it feels.
I think the liner was titanium too(lighter but not strong as steel). While it may be perfectly adequate, personally I did not like it.
To me, the Mili is a working knife...if defence were so impt to me, I would go for something else in the Spydie range. You have your Wegner, Lum G-10 Tanto, Gunting, Chinook, G-10 Police.....
