My favorite sheeple knife would be my Spyderco Dyad. It's small enough to not offend anyone, and the blade combo is neat as heck! I've gotten a few remarks on the agressive looking serrations on the sheepsfoot blade, but they quickly nod, grunt, and at least to pretend to understand when I explain that as a volunteer EMT, I may use the serrated blade to cut a person out of a car (never mind the fact that this is rarely the true case, but it does happen sometimes, and it placates them)
Another interesting note on a knife I made sheeple friendly, Which was my MT UDT When I first got it, I showed it around the security office, hospital,and Medical Transport company I worked at and the most frequent remarks I heard was "sharp, concealable, fast, dangerous" Then just for shucks and grins I tied a pink, purple, multiple colored lanyard on it (truth is that it made the knife lightning fast to get to) All of a sudden with a few girly colors, it was more frequently described as cute, handy, light, easy to carry. With the addition of a simple .35 piece of cord I was able to transfer a lethal weapon of assassins into a cute, handy lovable tool. go figure, eh?
Actually, I think I may pick up some of those "flip-its" depending on price. Seems they'd make good stocking stuffers around Christmas, and I may also hand some of them out in some of the classes I may end up teaching this year.
