i nick myself all the time and usually a band aid will suffice. two days ago i made a real rookie mistake with a mat knife. the blade entered the top of my finger....went all the way through...out the bottom and then out the tip. lots of blood. i wrapped a tea bag around the wound with tape and left it on for 24 hours. tea will stop the bleeding. when i took the tape off the tea had solidified around the wound. by slowly rinsing i got it all off and put anti biotic on and re bandaged. just a good way to stop bleeding.
