Spyderco is kind of fabless knife maker, you can think it's an American knife factory.
There are Moki, G. Sakai, Hiro, IC cuts, Hattori, Kai (for razors), Olfa, and more. Not sure but Lakota is also a Japanese knife maker.
They are all major knife makers, but most of utility knives like kitchen knives and hatchets, are made by nameless but skilled local smiths.
Hope this helps.
