Just my hand, with the big ones when their head pops into the hole I reach into the gill plate and lift them out and sometimes even just pull them out with the line since I usually get my big ones on tip-ups spooled with 40lb line. And when I'm handling them I like to support their belly with my other hand holding them horizonal, the way their used to, so I don't do damage to their vertebrae. And thats all I do. Personally I don't really like the idea of the lip grippers when I've seen guys just holding big fish vertical the entire time letting them flap around most likely hurting the fish, those fish are not used to have all their weight on their spine. However if used to just land them and then supported properly they are probably a good tool to have.
