I have just updated the hook-removal article to include information on how to use both the ‘loop’ and ‘forceps’ method one-handed to remove hooks from yourself. This is usually required when the hook is buried in a hand or arm.
When using the loop method, make the loop long enough to go over some immovable object, such as a tree branch. Hold down the eye of the hook and pull your hand away in the direction shown in the diagrams in the article.
If using long-nose pliers or forceps, hold the hook eye down with the thumb of the hand holding down the forceps.
