In response to a recent request from a friend who got a hook stuck in his face, here is a link on how to remove fishing hooks.
There are lots of good resources out there for fish hook removal so am not going to re-invent the wheel here.
The following link discussed both the string method and the push through and cut method for removing hooks.
But remember, an ounce of prevention is worth a pound of cure so make sure you look when casting and discuss casting with new fishing partners before going out.
Cheers from the Wild
