I have recently gotten into collecting knives and have been able to pull a lot of info from the product catalogs from all the major makers. Many have catalogs dating back a few years, but further than that they are not available. I run my own IT company and there is this resource http://www.cpu-world.com/ that has a very comprehensive list of all models and all relevant information for processors sorted based on maker and features. Does anything like this exist for knives?
