Good questions.
I just had this same converstation with another on this thread:

medical reasons
For a lot of people yes. Some of us prefer to cross stitch, or do needlepoint on flights. The guy next to you never reads cross stitch over your shoulder.
Also, I take flights frequently that are just overnighters, so I just have a carry-on bag so that I can avoid baggage claim hassles and delays. For those kinds of flights, it's a pain to strip my baggage clean of anything that may be contraband (utility tool, nail clippers, etc.).
Ballpoint pens are more dangerous than those scissors.
It isn't an issue of having them in-flight. It's an issue of not getting them back after they've been confiscated.
I keep a small screwdriver, swiss army knife and scissors (not to mention a nail clipper with file) in my briefcase for general use. They come in handy time and time again. Even if I don't use them on the flight it's a royal pain to have to remove them if I am going to fly and then be without them when I arrive.
PS, I would prefer the old lady next to me have a pair of sharp scissors that could be used if anyone tried to take over the plane than to be defenseless against whatever weapon a terrorist managed to smuggle on-board.
You can't do needlepoint, cross stitch, knitting or crocheting in flight without scissors.
"...OK, what do you need tools for in flight?..."
I haven't checked luggage underneath the plane in at least twenty years, except for when I go skiing and bring my equipment. My rollaway and small tote are the only bags I carry aboard. I would appreciate being able to cart my pocketknife and little flashlight so they're with me at my destination...and I can be on my way.
The simple fact-of-the-matter is that a modern commercial jetliner will never be hijacked again. Pocketknives should be the least of concerns with regard to airline security.

OK what do you need tools for in flt ?
Those of us who fly weekly would love to have our leatherman -- it is frequently good to have at the client site, at the hotel, etc. We don't like to check in luggage (which added an hour to my 8-hour commute yesterday).
Ever have an unraveling thread on a shirt? It would be nice to have a pair of scissors to clip it. Calling downstairs and either getting or waiting for (and tipping) a bellboy to bring a pair is a big pain in the butt.
You've obviously never had a $700 tool set stolen from checked luggage.
