A big carpet wouldn't require stitches, unless you pulled away. Trust me, I know, I had a 9'er tag my elbow for no apparent reason and it hardly broke the skin, just a few prics and a couple drops of blood.
By saying you want something handleable I think you mean a little more active than a ball python. Some ball pythons are more active than others, but most won't move around as much as some of the other snakes.
If you are only considering pythons here are my suggestions:
Any of the Liasis species(Australian/ New Guinea pythons i.e. macklot's pythons, water python's, savu python's etc). They aren't an "overplayed" snake and although most are nippy as babies they calm down well and don't get too big.
Carpet pythons-Jungle's tend to be the feistiest but they will calm down and are beautifyl.
Jampea Dwarf retic(male's)- Tend to stay small(6-7') and are beautiful and docile. Actually, almost all CB retics are calm but the mainland forms and other islands just get too big. My personal favorite snake is the retic so maybe I am biased but they are very, very, active.
Many people will say burms are a good snake as far as handling goes, which is true, until they are 15' and see you as a tasty treat.
Hope this helps, consider your choices and make the decision on the snake that you prefer most, but don't let the potential of a bite scare you from working with any beautiful snake, as almost any snake can be calmed with time and patience.
