I've been carrying, "old school" folders for about a year now, exclusively. Yes I could if I had to, but I recently picked up on the habit of carrying a fixed blade everyday, and in conjunction with my slipjoints, and traditional folding knives. As much as it pains me to say it, if I was regulated to just a folder I'd get back into the more modern stuff, and I still do own all of my Modern folders. Didn't sell anything, seeing as my taste change on a whim, for a long time. If I can have my fixed blade, then I don't need a one hander. Traditional pocket knife, and EDC sized fixed blade (modern or traditional or whatever) for me.
