My understanding of things:
-GEC limits the number of SFO orders and limits the accepted SFO order totals to 500 units to prevent GEC from becoming an SFO-exclusive knife manufacturer.
-GEC is still a small company, and they don't have much interest in pumping out a few thousand of the same models year round to satisfy demand. They limit production numbers in order to provide more patterns throughout the year.
-That being said, I'm quite certain that this last run of Beer Scouts/15s was the largest run GEC has ever done. This run of 74s seems quite large, as well, which may indicate that they are attempting to meet demand. Look at how many Beer Scouts/15s are still available from this last run (as well as 14s), and it would seem to me that GEC overshot their mark on demand, which is not good for them. They seem to be trying to figure it out, though. As far as "having a pretty good feel for models", Beer Scouts are probably right behind TC Barlows and NF Barlows as far as demand goes, and they are still readily available from every distributor that bought them. I'm sure they thought they would "vaporize in minutes" based off of how quickly previous runs sold out.
