Leeman:
I too have the SAK "Huntsman" model. Though mine is a much older model (25+ years) it still is going strong. I have had to replace the toothpick (4 times) Tweezers (once) and now will need to replace the screw for the scissors. Not too bad for the length of ownership. <img src="images/graemlins/cool.gif" alt="" /> I have also kept the knife, clean and sharp, which you should do with all knives, but some people I know won't bother. The most punishment I can recall having done to the knife is letting a so called professional sharpen the main blade. He about ruined it. I managed to locate another professional and he corrected the problem. Most interesting use? I used it to cut off a pair of Biker Boots on an ambulance call one-time. Not recommended for your own health and safety sake. <img src="images/graemlins/crazy.gif" alt="" /> The guy had tried to avoid a stupid "pull in front of him motorist" and hit a phone pole instead. Broke his lower leg. I was threatened by him for "cutting the boots" (note: cut along seam, easy repair) since I was also in Law Enforcement, I just reached into my pocket and showed him my badge. He became apologetic and the job was done.
Like Paul810 has said, it depends on the job and for what purpose you have in mind. Since I live in Idaho, not too many are offended by knives. If you just need something simple choose the "classic series." I might also note the added addition of a small lanyard to the keyring. I use a cellular phone size for mine and find it is much easier to retrieve from the fanny pack.
Take care,
