Hi Eugene,

Here is a link to a foxhole radio I built a number of years ago for
a demonstration/presentation I did.

I could not find any "blued" razor blades, so I used a regualr
one.

I had to heat it up with a propane torch until it was orange and
then quenched it in some cold water.

I then scraped it the blade up and another razor blade and it
worked great and tried it.

It worked great.

I had more trouble getting the enamel off of the coil windings
for the slider to work.
