An odd tool recently came into my possession.  It is a tubular looking
screwdriver, of some sort, that has an offset five-point star on one
end and the letters LD inscribe on the side.  On the other side it is
very similar with the exception that instead of a five point star it
is and 8 point start and instead of LD it has inscribed in it LB.  The
Channell Commercial Corporation makes it.  I have been on there web
site and have not been able to figure out what it does, but it appears
that they do not make it any more.  I am stymied. I am able to find no
reference to it on the web.  I am hoping that someone can help me
figure out what this anomalous tool is and where you can either buy or
sell them.
