All makers used various eagle suppliers and etch template suppliers. The SS makers used various rune button suppliers as well. Grip wood color is not fixed, except the Suhl makers used hard woods with a great finish.
But no other maker, in my opinion, used as many diverse components as EP&S. Even the Sigfried logo appears slightly different on many daggers.
I think that a lot of good daggers have been passed over because of this.
