Using large wire cutters, hold onto the shaft in the very first (top) thread and it'll work awesome. Of course, it can't cut into the shaft yet will not let the shaft slip or spin. You end with no chances of maring up the shaft when you hold in the groove of a thread. Didn't believe it myslef but it's worked great for years....and it's free!
