The following of Peanuts here is very strong. I have only had a few, and my first response when I got one in the mail was, What the heck ?
Must be some sort of a bad joke. But in the pocket it went. For the first few days, I was constantly checking to make sure it was still in there. Plus it was a good excuse to fondle and examine it. I honestly didn't give it a long enough run to make an honest opiniion, but I will say that whenever I did need it, it did exactly what was needed of it, for normal daily tasks.
That said, I was hooked on the mini trapper as soon as I got one. The first time I held one, I knew that wouldn't be the last one. It still is small enough to disappear in pocket, although I wear blue jeans 7 days a week. It feels like a bigger knife than it is, and fits my big hands perfectly. Not because it is a big knife, but the shape fills the hand nicely.
Its a very personal choice, so my recommendation would be to buy one of each pattern, and see which one really works for you. Not sure what your budget is, but quite a few folks here have bought Rough Riders in different patterns to try them out. By reports, they are a very decent knife, and can be had in different patterns and colors for around 10 bucks a piece.
