If you can't afford to get stitches and really need them, fishing line works pretty well. I know a lot of friends with no medical insurance that know how to suture their wounds with that stuff. It hurts like hell and has its own risk of infection if everything isn't sterilized, but if you have a cut that actually needs stitches and no money to get them they're a life saver.
I've also seen people hold their cuts together with super glue and duct tape.
Also, I once got cut just like this on the inside of one of my fingers. It was hanging a little over the edge of the sheath hole when I was pulling it out and it cut it right across the first crease in the finger. I've got medical though so I just went to the hospital and got stitches. It's hard not to get stitches on your fingers in these areas since the wound will open with just about any normal use unless you completely immobilize it.
