I'm a big Case collector, have been for years. Case makes wonderful knives that will last a lifetime. That said, the trapperlock is one of my least favorite patterns. The detent is not very positive, that puppy can and will open in your pocket. The light-duty lock combined with a loosely-fitted blade on bearings makes for a much more dangerous knife than a regular slipjoint (imho). I have cut myself with a trapperlock, a couple of times. I will never carry one again. If you get one, I recommend a sheath to keep the thing closed. I would recommend just about any other pattern over the trapperlock. For a good single blade in the same size range, the slimline trapper is much nicer.
For a secondary knife, you don't really need something full size. You'd be surprised what you can do with a teeny tiny peanut. With Cases, a little knife goes a long way.
