I've seen over the years various charts ranking "the most popular brands" for certain time periods, but recognized these ranking are actually very subjective to each collector's own preferences.
So, let me ask you- what are your favorite knife brands?
Schrade only old
Buck
Case
Eye Brand
Hen&Rooster
Ka-bar especially their folding hunter
Columbia River only old
I'm sure that there are some I did not mention that would hit me if you told me
