I have my 500 in my pocket this morning. I love this knife and agree with Imafritz that it's a perfect all-rounder knife.
It's nowhere near the heft or thickness of either a 110 or 112 and is so thin that it's very comfortable to pocket carry in jeans. I also prefer the drop point over the clip point of the 11/112 for EDC use by a very, very wide margin.
The 501 deserves a very close look too. For life in the office, I find that a knife in the 501 range is less upsetting to the local natives when deployed. But for me, blades in the sub 3" do just fine for general cutting but not so good for food prep.
If EDC use means pocket carry, food prep and heavy duty cutting chores around the yard or shop, I would suggest the 500 (over the 110 or 112). As an inexpensive alternative, my local Walmart still has the clipless version of 482 on sale for $17.
If EDC use means pocket carry and lighter general purpose cutting (but not food prep), I would suggest the 501. Would also suggest the shorter 501 if you tend to wear lighter slacks and prefer a slightly shorter and less noticeable knife.
Another comparison shot.

The 500 is in the center. The clipless 482 is just below it. I actually like the blade on the 482 better. The green knife at the bottom is an old Old Timer 5OT that is almost identical in size to the 501. The pictures are deceiving in a way. I find that the 501 (or my 5OT) is a much bigger step down in size than the tape measure indicates.
Hope some of this helps.
