Your premise is probably correct for 90% of the knife's potential use. It's the 10% I worry about. Gather 50' of poly, hemp or Manila line. Soak it and leave in a freezer for one hour. Now wrap yourself in it and jump into the shallow end of a swimming pool. For good measure lets imobilise your using arm. Have somebody toss a tarp over your head. You have a onehanded folder in your pocket and a sheath knife. For our second scenario sit in the park sandbox next Easter. We are hunting eggs, roots and water. Assume we don't have any improvised shovel and must use our knife. I discovered my RSK nearly imobile from lint and dust in my pockets gumming up in the viscous militec oil, even when applied sparingly ( working a waspy horse in a roundpen can stir up the ground!). This is more a maintenance headache, but again a consideration. Knives are just like firemaking gear. They are both so critical , predetermining to carry solely one is 'cutting' it close.
