My favorite unpopular knives are made by Camillus. Camillus doesn't get a ton of love around here, mainly because they used mostly stainless steel in their later years. They also adopted the use of mostly Delrin covers during the 1950's. Not the most photogenic or collectible type of knives for sure. They also did mostly contract work, so collections tend to look disjointed with all of the differing brand names.
But Camillus knives are a family favorite, living in Upstate New York, and we are constantly on the hunt for our favorite models. Camillus made some sensationally functional patterns, refined for over 100 years. Add in the detective work required to figure out what was made by Camillus and what wasn't, and you have a recipe for a lot of fun.
Today I'm carrying two Camillus contract knives; a Buck 301 and a Remington R-4. Both are stainless. Both are Delrin. Both are awesome. They represent what may be the most refined examples of the scout and large stockman patterns that I've ever used. Nothing particularly fancy, but they feel great in the hand, and are exceptionally efficient at getting the job done.
