there are lots of carving knifes for sale
No, there are not - unless you're looking at ads on ebay.com, where these restrictions don't apply.
EBay is very strict about the prohibition of knives. In fact, I suspect they may scan listings for attempts to sell knives here, instead of only waiting for other members to report them.
Are you sure you're not looking at listings in woodcarving hand tools, where carving knives are allowed?
