(A lot of time when you collect SAK's you end up buying them used in lots on Ebay and end up with duplicates)
The most often used in the above list are the Vic Huntsmans/Compacts, Leatherman Micras,Buck 110's.
I use Moras a lot and have 5 or so but they are all different models.
Knives i like enough to want to buy duplicates of would be- Spyderco Tenacious, Enzo Trapper, (little/tiny import model) Buck Trapper and more Moras of course, lol.
Corrections those are knives i like enough and can possibly afford to buy duplicates of!
(Pipe dream knives are another list entirely)
