Overload,
That is a nice collection. I know I am a sucker for good quality knives too, but I am just starting on mine. Where do you normally buy your knives? I have used Dave's Knife World and have had good luck with them.
All around: some from the makers, some from the knife boards, some from purveyors. Going to knife shows, like BLADE in Atlanta is popular. It's taken me years to amass my collection. There are many good Internet purveyors like bladeart.com, truenorthknives.com, edcknives.com and others. There are also some great retail stores, like Plaza Cutlery and the one mentioned above. The places I just mentioned are good sources for CUSTOM knives.
Production knives are a different story. There are a lot more places to get those. I've not used Dave's, but the web site looks good and has new stock, but they need to update their NEW ARRIVALS page, and their search engine is poor.
