I'm 56 years old, and I must admit, I sometimes look around and am amazed at the changes that have taken place during my lifetime. So many things have evolved, and of course that is a never ending trend. While things would stay pretty stagnant at times in world history, the advancement of technology has changed that drastically. If you were to be zapped ten to fifteen years into the future, you would likely be very amazed at the changes that happened during that time frame.
That brings me to what many of us think of as being traditional folding knives... I mostly mean knives like the Congress, Canoe, Peanut, Barlow, Toothpick, and other such classic patterns that we can easily relate to. Heck, even the Buck 110, seen by most youths as only being a good boat anchor.
I believe these knives are definitely all on their way out.
That does not mean totally disappear from being produced, but certainly relegated to a niche product. As long as some nostalgic and older folks are still alive, there will be a market for these knives, but the market is already much smaller than it once was, and although there will be a new maker here and there to offer and fill that niche, the overall trend will continue being that the traditional knife will be mostly a thing of the past.
This eventually happens with pretty much everything. New things come out, and the younger generations of people start adopting them as their norm. The future is with them... At least for a little while. Why do I say that? Well, because these younger generation folks that have formed new norms, will also age... And then they too will see that things have drastically changed within their lifetimes. They too will see this happen, and then even wonder how the newer generations of folks find this or that to somehow be better or more visually pleasing to what had been the norm.
This does not stop, I have embraced this fact. My younger friends at work have no interest at all in traditional folders, but they get pretty excited about getting the latest modern folder that just cost them a couple/few hundred dollars. They show me their new modern folders, and although I am polite and say nice things to them about their latest aquisitions... In reality their knives don't do anything for me. No matter how well made they may be, it just looks like a well made tool to me, nothing more. They themselves look at them as being a well made tool AND a thing of beauty.
Yup, it's just the process of time... things change.
Maybe some of our traditional knives will wind up in collections after we pass... But, just as likely that they will be seen by the newer generations as things to be discarded. Or, maybe loved ones will place them in boxes in attics and basements, where most will eventually be forgotten and left to start deteriorating to the point that eventually they too wind up getting discarded by them, or maybe by their children as they too grow and move on.
A very few will always be in some good knife collection or museum... This can all very well happen... History tends to repeat itself, and this process is no strange phenomenon.
Please forgive my long winded response to this topic.
