[Boatanchors] Racor Blade Rectification

[Duane Fischer, W8DBF]

Do any of you who served in WW2 remember what brand of razor blades the Army, or
other branch of the armed forces, issued to each person? 	
	
W8QLZ, Roy, who is 89 was telling me about the modified 'fox hole' radio he
built while at the WAR station in Maryland. He said they used the Marlin brand
of razor blade. Some of you have suggested that the Gillette blue blade was what
was used, not Marlin.  	
	
They will probably both work. 	
	
Question: exactly what made the Marlin or the Gillette razor blade work as a
diode for rectification? Some say it was the special electric printing of the
product name on the blade and others claim it was what the blade was made of.   

	
How about it you guys who were there in WW2 and used one of these infamous 'fox
hole' sets, what is the rest of the story?	
	
Thanks!
