How many knife forums are there on the Net?

[golok]

I know BF is currently the top dog as far as knife forums are concerned. But seriously though, are there an estimated 30 knife forums on the Internet?

This is just a guesstimate. Someone surely must have a verifiable answer to this question.

What is the Pull Factor with regard to this particular Bladeforums?
