Yeah, you can find almost any GEC you want, but it's often not a simple process, and this definitely deters "average Joe." He wants a good ol' American high quality knife, he hears GEC makes the genuine article. He checks it out: "Oh man, $80 for a knife? That's a lot of coin... Well, you get what you pay for, I guess. I want a stockman. That's the epitome of Traditional Knife, my dad and grandpa and great uncle all carried them.... I see GEC makes a few, and man, they're gorgeous!" Then he goes to order this Pattern 81, or 82, or 53, and discovers that exactly nowhere can he actually find the thing in stock, that it's been years since they were made, and that if he wants one he is going to have to pay even more money, and probably spend weeks hunting online, especially if he's at all picky about the aesthetics. If he's dedicated, this process might turn him into a collector. If he's not so dedicated, he'll throw in the towel and buy a Case or Buck or Rough Rider.
The problem is one of production capacity. GEC has made a lot of nice knife patterns over the years, but if their max capacity based on the 2015 figures is about 16,000 knives per year.... That's fairly finite, and there's not a lot they can do to increase it, that doesn't entail major risk. We all want to be able to go to our favorite dealer and choose from 40 patterns in stock or able to be backordered with delivery within a few weeks, in multiple interesting levels of trim and handle materials. But that's not possible unless GEC really scales up. It is frustrating to really want a particular knife and not be able to find it. I don't think the problem will get much better, unless another big economic downturn puts the hurt on the "luxury" purchase of pocketknives, as happened in 2008-2012 or so. The company has a lot of potential customers, they just have to figure out the best way to serve them. Make 32 runs a year of 500 knives? Rename themselves "BS Co" and make 1000 73s to keep the supply fresh, alongside 15,000 beer scouts?
I think they're doing the best they can, trying to keep current customers, attract new ones, please dealers new and old, and also keep making the knives they actually want to make.
