Lightfoot C4 - Opinions wanted

[Springer45]

I have never bought a custom knife before. I never even had a favorite designer until I noticed Greg Lightfoot's Full Contact Fighter a few months ago. Something about the shape of that blade appeals to me. Since then I've taken a liking to the C4. I like a few of his other designs as well but would someday like to own a C4 tanto.

Does anyone here currently own one and what do you think of it's usefulness and ergonomics?

Opinions from owners of other Lightfoot knives about the general quality of Mr. Lightfoot's designs are welcome also.
