This one is not, but there was the Spyderco Wegner, which is very close to the one in the pics (except that it has a round hole, obviously). The first model was a custom made by Phil Boguszevsky (and Tim Wegner), and it had Ti handles. Then Spyderco made it as a custom collaboration with G-10. About the same period came the Spyderco Mouse as well (with aluminium handles), also a collaboration with Tim.
After a while, Tim made his own company (Bladetech) and is now producing the knives you posted. They are quality knives, BTW.
