I really like the Mora Companions as well, they're cheap and good, and I like that the belt clip sheath can also be clipped onto your pocket (where I always wear mine)... I had swiss army knives and Buck knives, always lost them...
My fave buck knife was a promo gift with an Ingersoll Rand impact gun (with IR etched on it).. it was only a small knife, but a very nice one, had a loophole on the blade that you could get your thumb into and open one handed which was really nice
The Frosts knives were similar but I don't see them around much anymore
