Queen City Cutlery is a line made by Queen - working man knives with carbon (rather than stainless) steel. Northwoods has their knives produced by other companies, such as Queen and GEC. Remington also doesn't currently make knives of their own, but has them made by other companies.
Personally, my favorite companies are Case and GEC, because they represent 2 very different markets. Cases are relatively inexpensive, and there's nearly endless options when it comes to patterns and handles. Even moreso when you go back in time and consider vintage models or variants. On the other end of the spectrum is GEC. Only a comparatively handful of patterns, limited production, and not nearly as much variety when it comes to different handle materials. However, the quality is at the top of production traditional knives. If you want a Case with stag as nice as GEC uses, you'll be paying about as much as you would for a GEC. GEC uses amazing woods, but have very limited supplies.
