Checking a hook point using your finger is a skill that must be learned. Finger tips are very sensitive instruments but you will not be able to differentiate between a brand new hook point and a slightly rounded hook point the first time you check. To build on this habit, check every new hook you buy. New hooks should make you cringe when you push gently on the point. Compare the new hooks to used hooks in your box - do this on and off the water. You'll find that checking is easy when your hands are dry but more difficult when they are wet. You may also find it convenient to check all three points on a treble hook at once using your thumb, middle, and ring finger.
