This is the Smith Easy Fish Grip Mini. It's the 15cm size, which is no longer sold. This fish grip is designed for ease and usability! The Easy Fish Grip allows you to easily and securely hold fish. Furthermore, the rounded tips minimize damage to the fish's lower jaw. To use it, place one tip on the fish's lower jaw and squeeze until you hear a "click" at the first lock. To release the fish, squeeze further to unlock and open the tips. This is the perfect size for rockfish, black sea bream, medium-sized sea bass, trout, and more. I've only used it to grip fish a few times, but I've taken it to fishing spots, so there are some scratches and a little rust from use, but there are no problems with its functionality. This is a used item managed by an amateur, so please refrain from purchasing if you are sensitive to imperfections or seek a perfect product.
