Just like Ryx, a two blade Old Timer. And as others have stated, I would feel somewhat under dressed without it.
I used to carry a different knife each day. But for about a year now, I've carried a SOG fielder i also carry a Gerber multi plier between the two, I'm covered most of the time.
In addition to the Spyderco in my right pocket and Case in my left pocket I also carry a Leatherman Squirt in my left pocket.
True, but I wear a belt only. It even holds up under the added weight of other hardware of the bang bang type.
Right now I am carrying a Victorinox Compact It's pretty cool with large blade, large scissors and the multi, cap lifter, can opener and screwdriver. I use the cork screw and the pen is very handy.
Opinel here as well - dirt cheap, sturdy, sharp ... what's not to love? For traveling I have a Victorinox stored in my wash bag
