A Mini or Mikro Canadian is great as a fixed blade pocket knife for edc, and I'd feel fine with it as my only fixed blade during light camping, but I'd want something a little bigger to complement a SAK and machete for rougher camping. A knife this size would be a great substitute for your Woodswalker, though.
As for sharpening, my BR Mini Canadian's edge is easy to touch up by stropping. If I strop it a little after each session of use, it doesn't really need "real" sharpening. I usually strop it on its own sheath (Russell Woodswalker sheath), belt, or a chunk of cardboard.
Last week, however, I accidentally banged the edge on a stone hearth a couple of times while whittling up some slivers to start a fire. It is still sharp but I can feel a rough spot where I struck it. I'll need to sharpen it for real to take care of that. Does anyone know where to get 1000 and 2000 grit wet/dry sandpaper? I struck out at Home Depot.
