Well, I have already seen a couple retailers dropping basically all the decent brands and leaving only some CRKT, Gerbers and few cheap CS and straight Chinese brands...
More expensive knives are sold by internet shops mostly this days. And these knives are not the kind of merchandise which goes well with impulse buy. But the cheap staff in the range of 10 - 30 dollars is.
Keeping dealing with retail outlets which move less than 1500 dollars worth of merchandise a month - that is for busy fools. What do you think would be BM margin there, considering that they sell their knives at dealer's prices, not full retail?
That is all just my opinion. I might be wrong. But that sort of makes sense to me.
