I, too, am a sucker for the Wharncliffe. It`s a very utilitarian blade that really works for me. I also like the fact that it doesn`t scream "TACTICAL" when you pull one out.
But I have to agree with Brian, there is no shortage decent, affordable Wharncliffes on the market. (the Klotzli`s with the carbon fiber handles rule!) And I think cutfinger got it right when he pointed to the Centofante series as a Wharncliffe variant, even though I think it looks more like a Spike!
Unless Spyderco knows something we don`t, I`m not sure they need to dump yet another Wharncliffe on the market. That niche seems to be full right now. (Unless it was a custom collaberation of some sort, of course. Then all bets are off!)
