A needle can do more than fix your clothes.
Level of difficulty (1 being easiest, 10 being hardest): 5
It is a very real possibility that your clothes might catch on something and rip, and in that case, you can close the rip with dental floss and a needle. In the event that you rip your skin instead of your clothing , you'll need to close the wound. Make sure to sterilize the needle over a fire, and go ahead and stitch that cut closed. Covering it with a bandadna and dousing it in some liquor is also helpful if getting legitimate medical attention is not an option.
