I still tend to prefer a sharp knife. When backpacking I carry one of two things

1) a small opinel folding knife - when I carry this, I keep it's carbon steel blade nice and sharp - as since it only has one blade, I use it for everything. It's lighter than option number 2 below. However I have to buy another since I stupidly ended up with it in my carryon
in reno airport last fall and had to huck it out before going through security.

2) A small Swiss Army knife. - and yes it as scissors, and I agree with you on their usefullnes. I use the scissors, tweezers, toothpick and both blades extensively. In this case I tend to keep the larger blade merely decently sharp . I keep the small blade honed very sharp. I use the small blade pretty much only for fine work (ie. swiss army surgery <img src="/forums/images/graemlins/wink.gif" alt="" /> ) and the big blade an scissors a lot more often.

When hunting I tend to take number 1), or a Mora knife, and a wyoming knife, and then
I want them very sharp.
