Takes a bit of time for these, but I'd try for one recommended by Bill 
or one of these:


30 gauge, so if you want to use the stripper, that size wire will be 
needed.  They used to have
them with semi safe to use strippers for other sizes.  If you are really 
worried, get NoNics strippers
if you can find them.
