I voted "somewhat" only because I've been using knives since 1961 and collecting since 1975. My traditional knowledge is primarily about traditional fixed blade hunting knives. My slip joint knowledge is limited to mainly 2 brands, Western and Kabar. What I know about Camillus, Imperial, Utica, Primble, GEC, Ulster, Colonial, Boker, Case and all the other "traditional" traditionals would not even fill a thimble.
The bad thing is that I will never be able to learn everything about anything.
The good thing is that I will never run out of stuff to learn. All I have to do is pick another style or another brand.
