4. Use Super Glue to Seal Your Wound
A deep but small cut may not always be stoppable by the previously mentioned DIY techniques, but Super Glue should do the trick. Simply apply pressure to the wound to help it temporarily stop bleeding heavily, and clean up the area quickly with a towel or rag. Next, fill the wound with a squirt of Super Glue, and then wipe off the area with pressure again.
If there is still some fresh blood that comes off on your towel, apply a second thin layer of Super Glue to the top of your wound. You may need to repeat this process a few more times, but it will end up stemming the flow of blood altogether. This will work as a seal, but it is best if you can also put Rescue Tape on top of the finished result.
