For me, I wanted a traditional knife that I can give my kids some day that I used in Africa, I wanted a quality piece. Im NOT saying those less expensive knives arent quality by any means. In my mind, looking at the options GEC offers some "heirloom quality" knives. I will be using it every day, so it will be scuffed up and beat around, but thats part of the beauty IMHO.
It appears that you really like GEC knives. You should get a GEC and nothing that follows should change that. I'm not arguing in any way and actually, want to encourage you to follow your gut on this. If GEC makes you happy, you should carry a GEC and nothing else.
I do think you may be conflating price and durability/quality. As I look around my shop and think of what I have stashed in my bags, I can find the following knives, all dating from the 1970s or before and all having had a significant amount of hard use:
+ My grandfathers no-name 6" bowie from the 60s.
+ A Schrade H-15 5" fixed blade
+ 2 Ulster BSA/camper knives
+ An Opinel #8 (no passed along to a buddy in the trades who has been unable to break it in over a year of intentional abuse)
+ A Buck 110 and Buck 112 (both 2 dotters from the 70s)
Of these, only the Bucks would have been considered to be mid-tiered in price. All have nearly 50 years of use on them and all of them will likely go on to my kids provided they don't get sharpened down to stubs. My point in noting this is a very narrow one and one you should not worry about and it is this. Yes, a GEC will last your lifetime and will be able to endure what you dish out to it in Africa and be passed on to your kids. But the same is true for a currently made Buck 112, Case Sodbuster, Opinel or an (alox scaled) SAK.
By all accounts, GEC makes great knives. They've revived knife making in the region using mostly hand done methods. They have wonderful looking designs and all of these things make owning a GEC worth the money. In fact, that's all that is needed. If you love GEC, get a GEC.
Given the number of 50 (or more) year old Ulsters and Bucks and such available on auction sites, it's very hard to argue that the GEC will be any more durable than any number of less expensive traditionals. But, that shouldn't cause you to spend less or feel less good about spending more on GEC. That you love GEC more than any other brand is an important thing to know about yourself and it's quite enough.
