Nope. But if ya buy them Owners everyone is so high on, you might as well. The keepers on Owners really do suck. The ones I use are a little better, but come loose after a dozen or so fish.
The damikis are real cheap compared to other hooks that thick. Its a really thick hook even thought the description doesnt make it seem like that. Youd have a hard time bending it out for sure.
I dont usually get on them that good and by the time ive caught 12 at my home lake ill switch out for a new hook....but the damiki vipers are pretty strong but have no keeper worth anything.
I orderred Gamakatsu round bends to do the same for an upcoming trip to Amistad....my wallet hopes they are as thick and sticky so I dont have to shell out for flipping hooks at the local tackle shops. Probably gonna have to do that though LOL
