I value the compactness of smaller knives, the ease of carry and acess, the way they don't scare people, and how they do cut like lasers, and how good they are for precision work.
However, I am gravitating towards bigger folders. I find myself reaching for my Eagle Talon or Opinel No. 9 when I want a more traditional knife to carry. My Copperhead and Moore Maker Serpentine Stock and larger Boker Stockman are pushing the Medium Stockman (my most favoritist knife ever) and my Sodbuster Jr. and my 303 outta my pockets.
I even think I'm going to be a hypocrite and go against what I've been preaching and buy a Queen, either a Moutain Man or a large swing guard, in birdseye and D2. I go over to Eknifeworks and ogle not the Cases or Kershaws, but the Rough Rider clasp knives.
So, all in all, right now, I'd say I prefer bigger knives. But I prefer bigger everything, and I'm about 6'7". I wear a Tissot Quadrato Chrono, which is about 3.75 cm across. I wear size fifteen shoes, and I carry big knives.
