While reporting fakes here and to eBay gives us a warm fuzzy feeling, eBay cannot do anything unless the owner of the trademark, copyright, or patent that is being infringed has registered with their VeRO (Verified Rights Owner) program and is the party reporting the violation. That's actually reasonable, since eBay can't realistically be expected to know what every company produces, or ever produced and an unscrupulous seller report "your" auctions to increase the chance of someone bidding on theirs. But, when I look through the list of VeRO participants, Spyderco is not among them.
