Well KF ITK was THE place to be a few years back, unfortunately it's a ghost town these days. Things change and evolve, usually for the better. KKF has an amazing collection of makers, vendors, hobbyists and members. The mods aren't too shabby either...
If you want to talk about kitchen knives then none of the other forums come close. Knife forums with a sub forum for kitchen knives just don't cut it. Oh yeah and welcome yo.
