> I think that I was using the trademarked term much the way that any brand of facial tissue is referred to as Kleenex in conversation.
You did, and since you identified the actual manufacturer, and used the minimal amount of the trademark name to specify what you were talking about, you likely fall under fair use exemptions.
You are also probably covered under casual use, since you are not in the tool selling business, and the monitary damage is so small a court wouldn't even bother hearing it. (In fact, it might even be sanctioned for frivilous action, the profit lost is probably $8)
Add to that the fact that DCMA doesn't even cover trademarks, and the whole thing is a total farce.
But ebay has no balls, and who wants to spend thousands on legal fees proving a pointless point....*sigh*
