There is for sale by owner fixed blades, for sale by dealer, sale by maker, sale custom fixed blade, trade, with and the kitchen knife maker area. So yeah, it's a lot like a needle in the haystack if you only wanting kitchen knife. Could increase traffic to the site to reorganize it to give this area of interest its own sub forums. If the site can have a sub forum for one brand of folding knifes, why not for a whole area of interest such as kitchen?
If the site only wants to promote carry knifes then maybe let the kitchen vendor's know so they can find a forum that wants them. Seriously, this is an area of huge interest to a lot of people. I will stop here. It's food for thought.
