i've only been "around here" a few months, but it seems to me that where knives are concerned, there is no single truly comprehensive source of information. i have 4 knife reference books, have read 1000s of bladeforum posts, posted lots of questions, and use ebay to show me a wide spectrum of knives. also, i usually learn something from every knife i get. so, i think "knife knowledge" is gained piecemeal over time, and really, that's part of what makes it so enjoyable, there is always more to learn. i have about 25 or so Camillus knives to date, about 1/2 are vintage, and all are well made, with zero blade play and good springs and a good feel in the hand. i like these knives and Camillus may supplant Case and Queen in importance to my collection. get yourself a few and check them out first hand. roland
