How to remove a deep splinter
Try using tweezers.
If any part of the splinter is visible above the surface of your skin, try removing it with tweezers. Choose tweezers with a serrated inner edge.

Possible answers:
*This works best if you have jewelry on which the splinter is connected. Place a soft cotton swab at the beginning of the splinter, just above and over the area.
*These tweezers should be so sharp that they won't pierce skin easily. Close your hands over the splinter and hold them there until the splinter should come out.
*Hold the tweezers parallel to your skin. Insert a thumb into the space between the splinter and skin.
*Grab the tip of the splinter with a firm hold, and slowly pull it out. Sterilize the tweezers before using them.
The answer is:
Grab the tip of the splinter with a firm hold, and slowly pull it out. Sterilize the tweezers before using them.
