A plier for fishing is the most important function together with the blade. To remove the hook from a fish then you will need a device, some fish have small sharp teeth and some do
not. I have never had any luck with using gloves for this. The best is a plier or the hook disgorger function you find on traditional SAKs. No doubt the plier works best. It is possible to make one of wood too. To remove the hook is important for two reasons,
either to release the fish again or to reuse the angle or lure. Especially today it is important to have in mind that some fish are too small and must be released by law. It is important then that the fish will be able to live afterwards with the little as
possible injury on it. The pliers are needed for a controlled hook release. For smaller fish the needle nose pliers works the best. For large fish the blunt nose with wide construction works best. I have used Victorinox, Wenger and Leatherman tools with success.
It is important to rinse the tool after use around or in saltwater environments. Then use some oil. It is best with a bit too much oil and that the tool is dry before oiling. I use food safe oil!
It takes some practice with using a plier for releasing a hook and to get the touch for it. When you get the practice then there are no need for any force, it is a matter of a small twist, push and guide.
