KJ, I've often wondered what the secret is on the highly sought-after patterns too, or more accurately, why some of them are not big sellers. To start with, the #15 pattern is just a good mid-size knife, not too big and not too small. Plus any kind of a GEC Barlow seems to be a hot item. Some S&M barlows are sitting on the shelves with no apparent frenzy. However, there are still #15 Crown Lifters on the dealers' shelves, and personally I like the antique yellow bone. I can see why the Beer Scouts are sold out, because, well, it's a Beer Scout. But the Crown Lifters are basically the same knife, just without the bail and the Beer Scout embellishments. There are still lots of really nice 78 single blades available, but I understand that lots of them were made so it could be just a numbers game. In general, I've seen the SFO single blade models go very fast, it seems to be just that simple that they are viewed as more collectable and therefore desirable. I don't think there are any 78 SFOs still available. The appaloosa 78s were literally sold before GEC started making them. Another example, the 54 Big Jack SFO for KSF in muslin micarta is a classy looking knife, yet they still have some left probably because it's a 2-blade. So I'd have to conclude that a (1) single blade SFO, (2) barlow pattern, (3) in a GEC #15 frame seems to be the magic formula. ...Or just a Northwoods brand in any configuration, yeah, those are all magical too.
