I tried a lip grabber a few years ago and had too much trouble with it.  I was reading a post somewhere about landing northerns and one guy posted he lipped them.  Then he posted a picture of his son (I think) lipping a > 24” northern.  The kid was wearing a glove.  He explained that it was a standard hardware store leather glove that had been treated with water proofing.  For the last 3 years I have been using a glove on my left hand to land fish.  I use the gloves around camp for chores and cooking.  To water proof my gloves I use SNO_SEAL.   (You need to Login or Register; I work as much SNO_SEAL into the gloves as I can and use heat from the kitchen stove to help get more to soak into the leather. The gloves stay dry inside until they go in over the cuff. Small sish I grab from the top and no gil plate gets to me. I don’t lip northern. Large fish I reach under like has been previously described.  For the last 3 years I have come home from my trips with no cuts on my hands and I loose less fish.
