It does shock though. Perhaps because of the speed of the movement. So try not to suddenly pull away as this can hurt the snake (whose teeth are caught in you when you suddenly jerk your hand away).
Oh, interestingly, snake bites seem to bleed quite a bit for how minor the injury is. Curious thing. They bleed, then you wipe the blood away once and it stops. Odd wound.
Anywho, better to not get bitten if you can avoid it. I always use a pillow case if I'm doubtful about a snake's nervousness/handleability. Just put the pillow case over his head (chuck it if you must!), then grab his head/neck under the pillow case gently, but firmly enough so he can't bail on you. I then pass my snake's head to my other hand so I can get rid of the pillow case.
As soon as my grip is not a crushing grip of death, but a friendly, gentle grip that allows them to get their head and neck free, my snakes relax, realising I'm not trying to kill them, and are then handle-able. Getting them free and out of their enclosure seems to help, too.
Finally, when I'm handling one that I'm not confident in, I don't let it have access to strike my face at any time. I let it slide away from me quite a bit, (they don't like being held by the neck, so hold them back a bit from here by just putting your flat hand under them so they can slide away from you on it, then bring them back and let them do it again). Support their lower half with your other hand. My snakes seemed to calm down when I drapped them over my neck, too. I kind of rub one side and keep track of the head with my other hand. But my snakes are quite a bit bigger than yours.
Anywho, just remember, they are scared of you. So show them you mean them no harm while not getting tagged yourself! Oh, and don't smell like mice/rats. Don't attempt to handle soon after feeding. Or when approaching a shed.
