Nice pair, bdmicarta.
Never had a mini, always wanted to try one. I prefer the 805 to the 806 as well..I like the stout tip and overall blade shape. The full size carries well w/ the flat slabs as opposed to the -1101's w/ the rounded scales (still some of my all time favorites, just didn't carry as well in pocket) ..the flat slabs and, as was mentioned, the 3.9' blade, in a tighter package is why the 710 is my most carried..
As much as I love the Axis versions , the 800's are brilliant. Less quirks like blade play, loosening pivots as on some Axis..never had issue w/ liner locks..alway smooth like silk w/ great lock up..
When I first started in the obsession, I wanted nothing to do w/ liner locks..found out on a 910 that BM does/did them right. And I think the liners are Ti, both sides, on the 800's...plus, less parts than Axis...less places to fail or shit to go sideways....love the Axis but there is something special about the 800 series..
