Bolt Cutters
If the hook isn’t coming out with the dehooker, it’s time to grab the bolt cutters.
These will cut right through a 12/0 mustad J hook…
Or a 20/0 mustad circle hook.
The idea is to get the shark back into the water in less than a minute. If you keep them out any longer, release becomes harder. Especially while you are walking a fish out backwords into heavy surf.
