Spyderco brand ZDP-189 Delica4 reground by moi to have a much thinner blade (pining for Caly3 with ZDP-189 and carbon fiber scales)
Victorinox brand Tinker

Also often carry a Spyderco brand Lava or Dodo and used to EDC my Swamp Rat Howling Rat (got it back after selling it and need to make a new sheath). Will probably EDC the Howler again as it gets as sharp as I want and is tougher than any stainless (though I do loves me Lava and that ZDP-189 is beyond impressive for a decidedly not tough steel).
