The way I did it was to get a 17 gauge guitar string (local guitar
center sells strings individually). I took two one inch dia. Six inch
long dowels and drilled a hole in the center and put a slip around it.
Wrapped the string through the hole and around in the slit then through
the hole and twisted it together. I go through the hive slowly so I
don't slice to many bees, but I definitely will slice through the brood
in the comb that is cut.
