Could someone help me ID this?

[Fredo456]

Gentlemen,

I bought this razor in an antique store. The scales say Boker Brand, and the box says King Cutter. I have no doubt that they originally were together as part of the same razor.

The blade, however, gives me a lot more trouble. Actually, I'm pretty sure it was changed as there're grind marks on the scales at the pivot (from a dremel?) and not the same pinning. There's no King Cutter etching on it. The logo engraved appears to be a rooster (I saw a similar one on a Banty box on E-Bay) with the following engraving (the first line is barely readable, and all the lines I write here are part of what I see):

-PH_HA (with probably 2-3 more characters that can't be seen anymore)
N-Y
HOLLOW GROUND





So, what blade is this?

Thanks for any help.
