It's absolutely nothing personal, but we kinda have to be serious here. A Buck 110 is about the farthest thing from a hard-use, lifetime folder. I mean, less than optimal steel, it weighs like seventeen lbs., no pocket clip so you're forced to use a belt-pouch (not great for folks in an office environment), that weak little "pivot pin" of what, is it? Peened brass? No thanks.
I have three or four Buck 110s. They are all pristine, because I have never carried them. Just so many better knives out there, sorry. My opinion.
Not offended in any way. We are in agreement on several factors.
There were 2 main points I was trying to make. First is that the 110 has already been around for a "lifetime" and continues to sell. I may be wrong, but I don't believe ANY of the other knives mentioned in this thread can make the claim of being around for 50+ years, fundamentally unchanged. They do take a beating, and will certainly last the owner's lifetime, since they have already proven that. It's size is comparable or smaller than several of the knives mentioned previously. A pocket clip has little to do in the way of its lifespan or durability. As for the steel, as has been so often pointed out before, it's all in the heat treat.
The second I didn't weigh in on nearly so much, primarily because some would have taken offense, something I absolutely was not trying to do. But I will elucidate further now, PROVIDED, everyone understand that I am not bad mouthing anyone, their knives, opinions, or rational. That being said, if we all would take a moment to be honest with ourselves, and I include myself in this as well, an awful lot of knives are marketed and bought due simply for the buyer's ego gratification.
Some want to be the hip early adopter, being the first kid on the block to have the latest / greatest toy.
Some want to be with the "in crowd" owning "the best" to be included in the group. Hey we all have favorite brands we dig. But for some, it is a way to join the gang.
Some want to flaunt wealth, be it actual or illusion, by showing how much they spent on something, or only buying the ultra pricey products.
Some want to demonstrate how knowledgeable they are, be it on a brand, style, material, origin, what ever. We elevate ourselves because we know and demand the "fine points" that only the true believers know about.
We all do it in varying degrees, in one way or another. It is one of our basic characteristics of being human. But let's at least be honest about it. Like one of the earlier posters said - and my apologies for not giving them the proper citation credit here - "any well made knife will last a lifetime if used properly and taken care of".
