Not even close!
But I do know what you mean ..... if I had to pick one, I'd say the Old Timer Middleman Jack (33OT) that was owned by my grandfather. It's a great knife that I keep going back to, despite my occasional phases of carrying a SAK or Trapper or Buck 055 or Leatherman or Spyderco. Eventually I always come back to that 33OT.
The funny thing is, when I tell people it was my grandfather's, they naturally assume he carried it for many years and so forth. Not at all. In fact, he NEVER carried it.
See, when Pop passed away, among his things was this brand new 33OT that the kids at the elementary school where he volunteered gave him for Christmas one year. Having lost an arm in the Battle of the Bulge in WWII, Pop never carried a folder after that (though I'm certain he never pointed this out to "his kids" so as to not hurt their feelings). In addition to being a superb knife, it reminds me of how much love surrounded my grandfather wherever he went. He was loved by the children he helped as a volunteer in schools. He was loved by the teachers who taught him (as he earned his high school Graduation Equivalence Diploma well into his 60s - and then his AA degree, and finally a bachelors degree!). He was loved by the countless other recovering alcoholics he helped over the years. He was loved by his kids and his huge extended family. And he was loved by his youngest grandson, who worshiped him and was lucky enough to spend two or three summers road-tripping with him across the country ...... me.
