According to my friend and info which he gave me only original one knives were made by Emil Pasiek Design with EPDESIGN logo and serial number.
I've found info that only 3000 of them were made between 1992 - 1994.
There wasn't military version with sharpen/saw blade.
The Gerlach made were only for the civilian market but I'm not sure who made them.
I was always convinced that a military versions were made by Gerlach but I've never checked it.
I need to dig it a little bit more.
