yeah, lip grips can do damage, but I rarely use them,
only when i need to get the big toga to hand, then its layed out on the brag,
or when Im taking a freind, or family member out, they use the grips, saves them from dropping the fish. And grabbing a fish with me hand, done it many times, me hands are cut up pretty good.
I'll try to use the grips less, though it might be a while untill i can go fishing.
cheers
