[Boatanchors] Racor Blade Rectification

[Glen Zook]

You need a "heat" treated "blue blade". 
Unfortunately, those from the 1960s were not heat
treated but primarily "painted".  It is the heat
treatment that causes the formation of the oxide that
allows for r.f. rectification.

Some of you have suggested that the Gillette blue
blade was what was used, not Marlin.
