Update: the seller responded to my questions, saying:
"It's definitely a Chris Reeves & Bill Harsey Design, it's made in Italy specifically for Tactical & Survival Specialties Inc. (TSSI) As far as the Knife they modeled this one after, I have no idea, but I can 100% say it's not a knockoff. TSSI calls this knife the Falcon and I purchased the Falcon knife directly from TSSI in both the "Spear point" and the "Modified Tanto" point They also carry a limited edition Desert Falcon that comes in a wooden knife display and a company challenge coin."
Can anyone verify this?
It sure as heck looks like the Razionale, with decorative holes in the handle and partially-serrated blade.
