Tamara - nice Greco. I have one of his older, non-marked, knives. It's a Japanese style. I like some of his designs and he's an unusual character. I always enjoyed seeing him at the Blade Show every year.
I just never see his knives and here you've got a nice looking one. When I got mine, he was living in the swamp, and had no phone (or, didn't want anyone to have his number). If you wanted one of his knives, you had to write to him and he would send a Poloroid snapshot of what he currently had. An interesting gentleman.
Oops - I just realized I'm rambling and am hijacking this thread. Sorry!
I've love to find a 3" M64 and a 2" M64 (as well as a 2" M10).
